Question

Identify the reagents to be used to complete the given reaction.

• A. \( \text{Br}_2 / \text{CCl}_4 \) \( B = \text{aq. KOH} \) \( C = \text{NaNH}_2 \) \( D = \text{Red hot Fe tube} \)
• B. \( \text{NaBr} \) \( B = \text{aq. KOH} \) \( C = \text{CaC}_2 \) \( D = \text{Red hot Ni tube} \)
• C. \( \text{CH}_3\text{Br} \) \( B = \text{aq. KOH} \) \( C = \text{Conc. HCl} \) \( D = \text{Red hot Pd tube} \)
• D. \( \text{Br}_2 / \text{CCl}_4 \) \( B = \text{aq. KOH} \) \( C = \text{Conc. H}_2\text{SO}_4 \) \( D = \text{Red hot Cu tube} \)

Hint:

In organic reactions, halogenation with \( \text{Br}_2/\text{CCl}_4 \), followed by elimination using sodium amide, and further reduction with a red-hot metal tube can lead to the formation of aromatic compounds like benzene.
