Options

A ${HNO}_{2}, Fe / {H}^{+}, {HNO}_{2}, KI, {H}_{2}O / {H}^{+}$
B ${HNO}_{2}, KI, Fe / {H}^{+}, {HNO}_{2}, {H}_{2}O /$ warm
C ${HNO}_{2}, KI, {HNO}_{2}, Fe / {H}^{+}, {H}_{2}O / {H}^{+}$
D ${HNO}_{2}, Fe / {H}^{+}, KI, {HNO}_{2}, {H}_{2}O /$ warm

Correct answer

B. ${HNO}_{2}, KI, Fe / {H}^{+}, {HNO}_{2}, {H}_{2}O /$ warm

Step-by-step solution

The product formation takes by diazotisation of amine group followed by aromatic nucleophilic substitution reaction of iodide. Then converting nitro group into amine by reduction and again diazotisation followed by nucleophilic substitution reaction with warm water.
