Correct statements regarding alkyl halides (

R - X

) among the following are :
(A) Alcohol being less polar solvent as compared to water, alcoholic KOH favours elimination reaction with

R - X

.
(B) Order of reactivity towards

S_{N} 1

mechanism is

C_{6} H_{5} - CH_{2} - Cl > C_{6} H_{5} - CHCl - C_{6} H_{5}

.
(C) Non substituted aryl halides exhibit properties similar to alkyl halides.
(D) Vinyl chloride is an example of haloalkene and allyl chloride is an example of haloalkyne.
(E)

R - Cl

can be prepared by reacting

R - OH

with

SOCl_{2}

but

Ar - Cl

cannot be prepared by reacting

Ar - OH

with

SOCl_{2}

.

Choose the correct answer from the options given below :

(A)A, B and C Only
(B)B and D Only
(C)A and E Only✓ Correct
(D)D and E Only

Answer: (C)

Solution

Alcoholic KOH, in the less polar alcohol medium, favours loss of HX by elimination over substitution, so statement A is correct. For the

S_{N} 1

pathway the rate tracks carbocation stability, and the diphenylmethyl cation from

C X_{6} H X_{5} - CHCl - C X_{6} H X_{5}

is more stable than the benzyl cation from

C X_{6} H X_{5} - CH X_{2} - Cl

, so the order in statement B is reversed and it fails. Aryl halides are far less reactive than alkyl halides because the

C - X

bond gains partial double-bond character by resonance, so statement C fails. Allyl chloride is a haloalkene, not a haloalkyne, so statement D fails. Alcohols are converted to chlorides by

SOCl X_{2}

whereas phenols are not, so statement E is correct. The correct statements are A and E.
