Assertion: It is difficult to replace chlorine by `-OH` in chlorobenzene in comparison to that in chloroethane
Reason: Chlorine-carbon (C-Cl) bond in chlorobenzene has a partial double bond character due to resonance.

Options

A. Both A and R are true and R is the correct explanation of A
B. Both A and R are true but R is NOT the correct explanation of A
C. A is true but R is false
D. A is false and R is True

Answer

A

Explanation

Chlorobenzene is very less reactive to nuclophilic substitution reaction by OH group as Carbon-chlorine (C-Cl) bond in chlorobenzene has a partial double bond character due to resonance.
