The functional group is defined as an atom or group of atoms joined in a specific manner, which gives the chemical properties of the organic compound and are the centers for chemical reactivity.

3, is the correct answer

3 is the correct answer

3 is answer sure 3 is the correct answer

Functional group is an atom or a group of atoms which largely determines the physical and chemical property of the compound.

Commonly known as ethyl alcohol. Its chemical formula is C2H6O. Also can bewrittenas CH3CH2OH .It contains one methyl group (CH3-) , one methylene group (-CH2-) and hydroxyl group (-OH).Here (-OH) is the functional group. The molecules containing -OH group are alcohols.

Acetic acid is also known asethanoic acid, its chemical symbol is represented by CH3COOH. It contains the carboxyl group, -COOH. Members of this group (carboxylicacids) groups are polar substances, i.e their molecules can form strong hydrogen bonds with each other and also with water.

A functional group is a portion of a molecule that is a recognizable/classified group of bound atoms. In organic chemistry it is very common to see molecules comprised mainly of a carbon backbone with functional groups attached to the chain

Functional Group of propane is alkane

Ans :- Aldehydes

Aldehydesand ketones areorganiccompounds which incorporate a carbonyl functional group, C=O. The carbon atom of this group has two remaining bonds that may be occupied by hydrogen or alkyl oraryl substituents. If at least one of these substituents is hydrogen, the compound is analdehyde.

Option 2. All the mass of ethylene taken is converted to polyethylene, so the polymer molecular mass will be 100 g

explain it

as all the mass of ethylene converted to polythene..and ethylene was taken 100gm do polytheylene formed will be 100gm too

Thanks

Thanks

please complete the question. , what is the relation between hydrogen ans carbon is not clear..

Aluminium when heated with carbon forms aluminium carbide.On hydrolysis of this it gives aluminium hydroxide as precipitate and methane gas is releasedNow number of π bonds in methane is 0as carbon is bonded by 4 sigma bonds

the no. of atoms of O = 2 ,the no. of atoms of C = 4the no. of atoms of H = 4*2=8.

so, the molecular mass = 2*16+4*12+8*1 = 32+48+8 = 88 so vapour density is molecular mass/mass of H2 = 88/2 = 44.

Since there should be delocalised π-electrons, (b) is the correct answer

Nucleophilic substitutionis a fundamental class ofreactionsin which an electron richnucleophileselectively bonds with or attacks the positive or partially positive charge of an atom or a group of atoms to replace a leaving group; the positive or partially positive atom

Thank you narunkholi bro..

An electron withdrawing group will increase the de localization of negative charge and so it will increase the stability of intermediate.

When a neucleophile attacks, on the p- nitro Chlorobenzene ,the intermediate produced shows a negative charge on the carbon adjacent to the nitro group(-NO2) , which is delocalized outside of the ring by the oxygen of the nitro group. So, the intermediate becomes more stable in comparison with the Chlorobenzene where no such effect is applied.

Hence, due to more stability in intermediates, the p- nitro Chlorobenzene reacts waster than Chlorobenzene in neucleophilic substitution reactio

AB+ is the blood group which can receive from all the group but donates to the same group.

Abalanced equationis anequationfor achemical reactionin which the number of atoms for each element in thereactionand the total charge are the same for both the reactants and the products. In other words, the mass and the charge arebalancedon both sides of thereaction.

A balanced equation is an equation for a chemicalreactionin which the number ofatomsfor eachelementin the reaction and the total charge are the same for both thereactantsand theproducts. In other words, the mass and the charge are balanced on both sides of the reaction.

Also Known As:Balancing the equation, balancing the reaction, conservation of charge and mass.

Examples of Unbalanced and Balanced Equations

An unbalanced chemical equation lists the reactants and products in a chemical reaction but doesn't state the amounts required to satisfy conservation of mass. For example, this equation for the reaction between iron oxide and carbon to form iron and carbon dioxide is unbalanced with respect to mass:

Fe2O3+ C → Fe + CO2

The equation is balanced for chargebecause both sides of the equation have no ions (net neutral charge).

The equation has 2 iron atoms on the reactants side of the equation (left of the arrow), but 1 iron atom on the products side (right of the arrow). Even without counting up the quantities of other atoms, you can tell the equation is not balanced. The goal of balancing the equation is to have the same number of each type of atom on both the left and right sides of the arrow.

This is achieved by changing the coefficients of the compounds (numbers placed in front of compound formulas). The subscripts are never changed (small numbers to the right of some atoms, as for iron and oxygen in this example). Changing the subscripts would alter the chemical identity of the compound!

The balanced equation is:

2 Fe2O3+ 3 C → 4 Fe + 3 CO2

Both the left and right sides of the equation have 4 Fe, 6 O, and 3 C atoms. When you balance equations, it's a good idea to check your work by multiplying the subscript of each atom by the coefficient. When no subscript is cited, consider it to be 1.

It's also good practice to cite the state of matter of each reactant. This is listed in parentheses immediately following the compound. For example, the earlier reaction could be written:

2 Fe2O3(s) + 3 C(s) → 4 Fe(s) + 3 CO2(g)

where s indicates a solid and g is a gas

Balanced Ionic Equation Example

Inaqueous solutions, it's common to balance chemical equations for both mass and charge. Balancing for mass produces the same numbers and kinds of atoms on both sides of the equation. Balancing for charge means the net charge is zero on both sides of the equation. The state of matter (aq) stands for aqueous, meaning only the ions are shown in the equation and that they are in water. For example:

Ag+(aq) + NO3-(aq) + Na+(aq) + Cl-(aq) → AgCl(s) + Na+(aq) + NO3-(aq)

Check that an ionic equation is balanced for charge by seeing if all of the positive and negative charges cancel each other out on each side of the equation. For example, on the left side of the equation, there are 2 positive charges and 2 negative charges, which means the net charge on the left side is neutral. On the right side, there is a neutral compound, one positive, and one negative charge, again yielding a net charge of 0.

a balance chemical equation is an equation for a chemical reaction with the number of atom for each element in the reaction and the total charge are the same for both reactants and the product another word the mass and the charts are balanced on both sides of the reaction

when both side equation is equal for doing reaction

The reaction in which one (or more )hydrogen atoms of a hydrocarbon are replaced bysome other atoms is called a substitution reaction.

A good example of a substitution reaction ishalogenation. When chlorine gas (Cl-Cl) is irradiated, some of the molecules are split into two chlorine radicals (Cl.) whose free electrons are stronglynucleophilic. One of them breaks a weak C-Hcovalentbond and grabs the liberated proton to form the electrically neutral H-Cl. The other radical reforms a covalent bond with the CH3.to form CH3Cl (methyl chloride).

option D.

As there will be no. back side attack or inversion possible for the nucleophile.

Aldehydesare usuallymore reactivetoward nucleophilic substitutionsthan ketonesbecause of both steric and electronic effects. Inaldehydes, the relatively small hydrogen atom is attached to one side of the carbonyl group, while a larger R group is affixed to the other side.

question clear please

how it will be 0can you please explain briefly in formula

From ideal gas eqn. PV = nRT,

moles for O2 => PV/RT => 1*1/RT

no. of molecules,

N = Na/RT............(1)

SIMILARLY FOR SO2,

moles of SO2 => PV/RT => 1*2/RT

no. of molecules,

M = 2Na/RT........(2)

divide both the eqns. we get,

N/M = ½

M = 2N

thnx for the help behen

Thechemical equationneeds to bebalancedso that it follows the law of conservation of mass. Abalanced chemical equationoccurs when the number of the different atoms of elements in the reactants side is equal to that of the products side.Balancing chemical equationsis a process of trial and error

An equation having an equal number of atoms of each element on both the sides is called a balanced chemical equation.

According to this law, mass can neither be created nor destroyed. In other words, the total mass of reactants should be equal to the total mass of the products in a chemical equation.

Therefore, the total number atoms of each element participating in the reaction must be equal on both sides of the chemical equation i.e. before and after reaction. Hence, it is for the above reason that a chemical equation should be balanced.

If in a chemical equation the total number of atoms in the reactant side are equal to the total number of atoms in the product side then the chemical reaction is said to be balanced.

The chemical reaction should be balanced show that it can follow the law of conservation of mass.
