Sodium phenoxide when heated with CO2 under pressure at 125° yields a product which on acetylation produces C. The major product C would be:

1. OH | C6H3—COCH3 | COCH3
2. OH | C6H4—COCH3
3. OCOCH3 | C6H4—COOH
4. OCOCH3 | C6H4—COOH

Correct answer: OCOCH3 | C6H4—COOH

Solution

The correct option represents the product formed from the reaction of sodium phenoxide with carbon dioxide, which leads to the formation of a carboxylic acid. Upon acetylation, this carboxylic acid is converted into its corresponding acetyl derivative, resulting in the structure shown in the correct option.
