Question

Statement I Benzonitrile is prepared by the reaction of
chlorobenzene with potassium cyanide.
Statement II Cyanide `(CN^(-))` is a strong nucleoohile.
A. Statement 1: is true Statement 2: is true, Statement 2 is the correct explainion of Statement 1
B. Statement 1 is true, Statement 2 is true, Statement 2 is not the correct explainion fo Statement 1.
C. Statement 1 is true, Statement 2 is false.
D. Statement 1 is false, Statement 2 is true.

Answer 1

Aryl halides do ot undergo nucleophillic substituion reaction under ordinary conditions. Thus, benzonitilie is not prepared by the reaction of chlorobenzene with `KCN`
Cynaide `(CN^(-))` is a strong nuclephile. Hence, statement 1 is incorrect, but statement 2 is correct.
