The reaction is not possible because Nu faces steric hindrance on attacking the leaving group.
Option: (a)
Explanation:
- Nu stands for nucleophile. when a nucleophile is added to a benzene ring it may face steric hindrance.
- Steric hindrance means not letting the nucleophile to come in contact with the benzene ring due to repulsion by the neighbouring group.
- Some of the group such as nitro and amine destabilizes the benzene ring. Some of the group are so huge in structure that prevent the nucleophile to come in contact with benzene.
