Vedclass · Accepted Answer

$A$ = $2,4,6-$trinitrobromobenzene,$B$ = $2,4,6-$trinitrophenol (picric acid)

Vedclass · Answer

(A) The reaction of bromobenzene with concentrated $HNO_3$ (nitration) leads to the formation of $2,4,6-$trinitrobromobenzene $(A)$ due to the strong activating effect of the three nitro groups. Subsequent treatment with $NaOH$ followed by $HCl$ (nucleophilic aromatic substitution) replaces the bromine atom with a hydroxyl group to form $2,4,6-$trinitrophenol,commonly known as picric acid $(B)$.

Identify $A$ and $B$ in the following reaction sequence.
