Question 7 - 2021 (25 Feb Shift 1)

Identify A and B in the chemical reaction.

[Structure: Cyclohexane with $\text{OCH}_3$ and $\text{NO}_2$ groups $\xrightarrow{\text{HCl}}$ A (Major) $\xrightarrow{\text{NaI, dry acetone}}$ B (Major)]

(1) A = [Structure: Chlorocyclohexane with $\text{NO}_2$ and $\text{OCH}_3$]; B = [Structure: Iodocyclohexane with $\text{Cl}$ and $\text{NO}_2$]

(2) A = [Structure: Chloro derivative with $\text{OCH}_3$ and $\text{NO}_2$]; B = [Structure: Iodo derivative with $\text{NO}_2$]

(3) A = [Structure: Chloro derivative with $\text{OCH}_3$ and $\text{NO}_2$]; B = [Structure: Iodo derivative with $\text{OCH}_3$ and $\text{NO}_2$]

(4) A = [Structure: Chloro derivative with $\text{NO}_2$]; B = [Structure: Iodo derivative with $\text{OCH}_3$ and $\text{NO}_2$]
