Question

What is the structure of C ?

• A.
• B.
• C.
• D.

Answer 1

The Correct Option is A

The chemical process comprises a Friedel-Crafts acylation, a Clemmensen reduction, and a dehydration.

1. Benzene reacts with succinic anhydride via Friedel-Crafts acylation, catalyzed by \(\text{AlCl}_3\), to produce compound A.
2. Compound A is then subjected to Clemmensen reduction using zinc amalgam (Zn-Hg) and hydrochloric acid (HCl), converting the carbonyl group to a methylene group (\(\text{—CH}_2—\)) and yielding compound B.
3. Compound B undergoes dehydration with concentrated sulfuric acid (\(\text{H}_2\text{SO}_4\)) to form compound C, involving the elimination of a water molecule and the creation of a double bond.

Compound C is the final product of this sequence.

Structure 1 corresponds to compound C.

Therefore, Structure 1 accurately represents the final structure of compound C.
