Question

Predict the product 'B'

• A.
• B.
• C.
• D. None of the above

Answer 1

The correct option is D None of the above

First step in the given reaction is electrophilic aromatic substitution reaction.
The $N{O}_2$ group is a deactivating and meta directing groups. Hence the product 'A' is meta chloro nitrobenzene.

The reagents of the second step tends to nucleophilic substitution reaction on product 'A'.

For $S_{N}Ar$ to occur, the electron withdrawing group should present at the ortho or para position of leaving group $(-Cl)$.
But here it is at the meta position so the compound 'A' does not undergo nucleophilic reaction.
