\[ \text{Ph–CH(OH)–CHO} \xrightarrow[\text{H}_2\text{O}]{\text{HO}^-} Q \] P and Q are isomers. Identify Q.
\[ \text{Ph–CH(OH)–CHO} \xrightarrow[\text{H}_2\text{O}]{\text{HO}^-} Q \] P and Q are isomers. Identify Q.
Show Hint
- \(\text{Ph–CH}_2–\text{COOH}\)
- \(\text{Ph–COOCH}_3\)
- \(\text{H–CO–CH}_2–\text{O–Ph}\)
- \(\text{Ph–CO–CH}_2\text{OH}\)
The Correct Option is A
Solution and Explanation
Step 1: Given compound undergoes base-catalyzed rearrangement.
Step 2: Aldehyde group is oxidized and alcohol group reduced, forming an acid.
Step 3: Resulting isomer is phenylacetic acid.
