10.Name a solid which show both schottky and frenkel defect.

Answer»

Schottky defect, basically a vacancy defect, arises in ionic crystals when equal number of anions and cations are missing from their normal lattice sites, resulting in the formation of a pair of holes.

Schottky defect is generally found in strongly ionic compounds having high coordination number and made up of anions and cations of nearly same size.

On the other hand Frenkel defect arises when a cation leaves it's normal lattice position and occupies an interstitial position.

Frenkel defect is generally found in compounds having low coordination numberand made up of canions and cations of widely different sizes i.e., anion much larger than cation.

Although these conditions seem to be just opposite to each other, yet AgBr shows both the defects. It is because AgBr crystal has a coordination number of 6 which is neither high nor low. The radius ratio of AgBr is also intermediate, thus AgBr satisfies the conditions to exhibit both type of defects.

P.S.: frenkel defect is more commen in AgBr because silver ions due to their small size easily occupy interstitial sites while comparitively larger bromide ions doesn't leave their position that easiy.

Effects of Schottky and Frenkel Defects

Answer»

A Schottky defect is a type of point defect in a crystal lattice named after Walter H. Schottky. ... In ionic crystals, the defect forms when oppositely charged ions leave their lattice sites, creating vacancies. These vacancies are formed in stoichiometric units, to maintain an overall neutral charge in the ionic solid.

A Frenkel defect or dislocation defect is a type of defect in crystalline solids where in an atom is displaced from its lattice position to an interstitial site, creating a vacancy at the original site and an interstitial defect at the new location without any changes in chemical properties.

16. Percentage composition of hydrogen in ethane isAno

Answer»

The% w/wofHinC2H6 [ethane]is:

% H= (MH,tot/MC2H6) ×100%

where:

MHis themolar mass of hydrogen,1.0079 g/mol, andMH,totis thetotalmass contributed by hydrogen in the compound. There are6equivalents of hydrogen in ethane, so we need to account for that.

MC2H6is themolecular mass of ethane, which is the sum of the atomic masses of carbon and hydrogen.

MC2H6=2×12.011+6×1.0079=30.069 g/mol

Hence, the% w/wofHis:

% H= 6×1.007930.069×100%

=20.11%

8] Explain why boiling point of inert gases increases with increases in atomic mass.

Answer»

The melting and boiling points of noble gases are very low in comparison to those of other substances of comparable atomic and molecular masses. This indicates that only weak van der Waals forces or weak London dispersion forces are present between the atoms of the noble gases in the liquid or the solid state.

The van der Waals force increases with the increase in the size of the atom, and therefore, in general, the boiling and melting points increase fromHeHetoRnRn.

Helium boils at−269∘C−269∘C. Argon has larger mass than helium and have larger dispersion forces. Because of larger size the outer electrons are less tightly held in the larger atoms so that instantaneous dipoles are more easily induced resulting in greater interaction between argon atoms. Therefore, its boiling point (−186∘C−186∘C) is more than that ofHeHe.

Similarly, because of increased dispersion forces, the boiling and melting points of monoatomic noble gases increase from helium to radon.

because his orbital is full

because inert gases have zero electron in their valence shell as their outermost shell is completely filled have 8 e- so they are placed in zero group

they have complete octet .....do not require any gain or lose of electron

because they found late

inert gases placed in zero group because they have it electrons in the outermost balance and zero group is also known as 18 group so 8 electrons in valence shell represents the 18 group and they are most stable as they do not react with any element element in zero group are known as noble gases

because of their symmetric outermost electronic configuration of (nS2nP6) except He(1S2) they are most stable do not undergo any chemical reaction (except Xe) are kept in group 18 which is also zero group

because the outermost shell of inert gas is completely filled

Because their outermost orbit is complete.in mendeleevs original periodic table there was no place reserved for noble gas.they was discovered in end of 19th century.so mendeleev created zero group without disturbing original periodic table.

Q.5-Define (a) Lattice Enthalpy (b) Bend Order.

Answer»

(I) Lattice Enthalpy:-The lattice energy of a crystalline solid is a measure of the energy released when ions are combined to make a compound. It is a measure of the cohesive forces that bind ions. Lattice energy is relevant to many practical properties including solubility, hardness, and volatility.

(ii)Bond number is the number of electron pairs between a pair of atoms. For example, in diatomic nitrogen N≡N the bond number is 3, in acetylene H−C≡C−H the bond number between the two carbon atoms is also 3, and the C−H bond order is 1. Bond number gives an indication of the stability of a bond.

In organic chemistry, an alkane, or paraffin, is an acyclic saturated hydrocarbon. In other words, an alkane consists of hydrogen and carbon atoms arranged in a tree structure in which all the carbon–carbon bonds are single. Alkanes have the general chemical formula CₙH₂ₙ₊₂.

Alkenes, also known as olefins, are organic compounds that consist of carbon and hydrogen atoms with one or more carbon-carbon double bonds in their chemical structure.Alkenesare unsaturated hydrocarbons. ... We can see two carbon atoms that are bonded together with a double bond, and they can be illustrated in two ways.

In other words, an alkane consists ofhydrogenandcarbonatoms arranged in atreestructure in which all thecarbon–carbon bondsaresingle.[1]Alkanes have the general chemical formula CnH2n+2. The alkanes range in complexity from the simplest case ofmethane(CH4), wheren=1 (sometimes called the parent molecule), to arbitrarily large and complex molecules, likepentacontane(C50H102) or 6-ethyl-2-methyl-5-(1-methylethyl) octane, anisomeroftetradecane(C14H30).

Alkanesare chemical compounds that consist of carbon (C) and hydrogen (H) atoms, so they are also called hydrocarbons. ... Taking a look at ethane and pentane, thesealkanesare referred to as saturated because they only contain single bonds, and because of that, each carbon atom is saturated with hydrogen atoms.

alcoholdoalkane.

Answer»

Dehydration to alkenes. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Because the elements of water are removed, this reaction is called a dehydration.

The dehydration reaction of alcohols to generate alkene proceeds by heating the alcohols in the presence of a strong acid, such as sulfuric or phosphoric acid, at high temperatures.
