Nucleophlic substitution reaction defination In alkyl halides the halogen atom displaced by nucleophile ​

Answer»

tion:-In organic chemistry and inorganic chemistry, nucleophilic substitution is a fundamental class of reactions in which an electron rich nucleophile selectively 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 is referred to as an electrophile. The whole molecular entity of which the electrophile and the leaving group are part is usually called the substrate. The nucleophile essentially attempts to replace the leaving group as the primary substituent in the reaction itself, as a part of another molecule.The most general form of the reaction may be given as the FOLLOWING:NUC: + R-LG → R-Nuc + LG:The electron pair (:) from the nucleophile(Nuc) attacks the substrate (R-LG) forming a new bond, while the leaving group (LG) departs with an electron pair. The principal product in this case is R-Nuc. The nucleophile may be electrically neutral or negatively charged, whereas the substrate is typically neutral or positively charged.An example of nucleophilic substitution is the hydrolysis of an alkyl bromide, R-Br, under basic conditions, where the attacking nucleophile is the OH− and the leaving group is Br−.R-Br + OH− → R-OH + Br−Nucleophilic substitution reactions are commonplace in organic chemistry, and they can be broadly categorised as taking place at a saturated aliphatic CARBON or at (less often) an aromatic or other unsaturated carbon centre. * Mark as Brainlist ANSWER I HOPE THIS WILL HELP YOU

Why does sulfur dioxide has a dipole moment

Answer»

because This molecule does not have a permanent dipole moment (i.e., the dipole moment of CO2 is ZERO). The requires the molecule to be linear because OXYGEN is more ELECTRONEGATIVE than carbon and therefore the C=O. ... The bonds in SO2 are also polar as the electronegativities of S and O are different, just like CO2.

If the UV calibration period is after 6 month then what we do if uv not showing proper result before that​

Answer»

olet-visible (UV-Vis) spectroscopy is one of the most POPULAR analytical techniques because it is very versatile and able to detect NEARLY every molecule. With UV-Vis spectroscopy, the UV-Vis light is passed through a sample and the transmittance of light by a sample is MEASURED. From the transmittance (T), the absorbance can be CALCULATED as A=-log (T). An absorbance spectrum is obtained that shows the absorbance of a COMPOUND at different wavelengths. The amount of absorbance at any wavelength is due to the chemical structure of the molecule.

Why inert gas have lowest E.A​

Answer»

toms have low ionization ENERGY and low electron AFFINITY. Therefore, they tend to lose ELECTRONS and do not tend to gain electrons. ... Any electrons added to a noble gas would have to be the first electron in a new (larger) energy level. This CAUSES the noble GASES to have essentially zero electron affinity.

What is moseley periodic table?​

Answer»

HEY FRIEND LET ME HELP YOU HENRY Moseley (1887–1915) subjected known ELEMENTS to x–rays. He was able to derive the relationship between x–ray frequency and number of PROTONS. When Moseley arranged the elements according to increasing atomic numbers and not atomic masses, some of the inconsistencies associated with Mendeleev's table were eliminated. The modern periodic table is based on Moseley's Periodic Law (atomic numbers).He suggested that instead of arranging elements in the ascending order of their atomic masses, they should be arranged in the ascending order of their atomic numbers.

How to find which is central atom in compound?

Answer»

1: Compare ElectronegativityThe ELECTRONEGATIVITY of an ELEMENT is its propensity to attract ELECTRONS, and the element in a COMPOUND with the lowest electronegativity is usually the central one. The EXCEPTION to this rule is hydrogen, which is never the central atom except in the H2 molecule.

What are covalent compounds ? Give properties and structural formula of covalent compounds. Give one example.​

Answer» EXPLANATION:Covalent bonds are characterized by the sharing of electrons between two or more atoms.ITS properties are,:At room temperature and normal atmospheric pressure, covalent compounds MAY exist as a solid, a liquid, or a gas.covalent compounds do not exhibit any electrical conductivity, either in pure form or when dissolved in water.The absence of charged ions is the main reason behind this. An exception to this is graphite.Covalent compounds do not possess polar CHARACTERISTICS as a general property. Therefore, these compounds are INSOLUBLE in water.Example: METHANE

State and explain markovikov's rule ​

Answer»

e states that with the addition of a protic acid HX to an asymmetric alkene, the acid hydrogen (H) gets attached to the carbon with more hydrogen substituents, and the halide (X) group gets attached to the carbon with more alkyl substituents.=> When a protic acid HX (X = CL, Br, I) is ADDED to an asymmetrically substituted alkene, addition of acidic hydrogen TAKES place at the less substituted carbon ATOM of the double bond, while halide X is added to the more alkyl substituted carbon atom

Calculate the pH of a 0.10 M ammonia solution.

Answer»

H2O → NH4+ + OH- KB  = [NH4+ ] [OH- ]    =  1.77 x 10-5           [NH3]Before neutralization,[NH4+ ]  = [OH-] = xThusKb  =   x2    = 1.77x 10-5        0.10Hence x = 1.33 x 10-5 = [OH-]  Now Kw = [H+][OH-]So [H+]  = Kw/ [OH-] = 10-14 / 1.33x 10-12 = 7.51 x 10-12       p H = - log(7.51 x 10-12) = 11.12On ADDITION of 25 ml of 0.1 M HCl solution to 50 ml of 0.1 M ammonia solution , 2.5 MOL of ammonia are neutralized. The resulting 75 ml solution CONTAINS the remaining unneutralised 2.5 mol of NH3 molecules and 2.5 mol of NH4+.                                         NH3    + HCl  → NH4+   + Cl-                                       2.5         2.5          0             0 At equilibrium                     0            0            2.5        2.5The resulting 75 ml of solution contains 2.5 mol of NH4+ ions and 2.5 mol of uneutralised NH3 molecules. This NH3 exists in the following equilibrium.NH4OH     ⇌      NH4+     + OH-0.033 M- y      y                  yWhere y = [OH-] = [NH4+]The FINAL 75ml solution after neutralization already contains 2.5 mol NH4+ ions, thus total concentration of NH4+ ions is given as:[NH4+]  = 0.033 + yAs y is small, [NH4OH] = 0.033 M and [NH4+] = 0.033MKb =  [NH4+]  [OH-]   = y (0.033)  = 1.77x 10-5 M            [NH4OH]          (0.033)Thus , y = 1.77 x 10-5 = [OH-][H+] = 10-14             = 0.56 x 10-9        1.77 x 10-5 Hence p H = 9.24
