Question

In both alkyl halides and aryl halides, the halogen (X) atom is attached directly to the carbon atom. They are expected to exhibit similar reactivity. However, aryl halides are comparatively very little reactive, particularly towards nucleophilic substitution reaction. for example, hydrolysis of ethyl chloride occurs by simply boiling with aqueous KOH. ON the other hand, the alkaline hydrolysis of chlorobenzene requires a very high temperature (623K) as well as a very high pressure.
Q. The halide which does not give any precipitate when warmed with alcoholic `AgNO_(3)` solution is:
A. chlorobenzene
B. Benzyl chloride
C. Allyl chloride
D. Tert-butyl chloride.

Answer 1

Correct Answer - A
Chlorobenzene does not react with `AgNO_(3)` because the cleavage of `C-Cl` bond is very difficult due to partial double bond character.
