Question

15. The compound that is more reactive
towards S1 is
(1) methyl chloride
on
(2) ethyl chloride
(3) 2-chloropropane
(4) 2-chloro-2-methyl propane​

Answer 1

15. The compound that is more reactive  towards S1 is

(1) methyl chloride

(2) ethyl chloride

(3) 2-chloropropane

(4) 2-chloro-2-methyl propane​

Required answer:

SN1 reaction involves the formation of carbocation intermediate. More the stability of carbocation more is the reactivity of alkyl/aryl halides towards SN1 reaction. Thus, C6H5C(CH3)(C6H5)Br is most reactive towards SN1 reaction. SN1 reaction involves the formation of carbocation intermediate.
