Question
Chlorobenzene is extremely less reactive towards a nucleophilic substitution reaction. Give two reasons for the same.
✓
Answer
- Due to resonance/diagrammatic representation, $C-Cl$ bond acquires a partial double bond character which is difficult to cleave.
- Due to $sp^2$ hybridisation of $‘C’$ of $C-Cl$ bond.
- Due to unstable phenyl cation.
- Due to repulsion between nucleophile and electron rich arenes.
