Q.
Aldehydes Ketones and Carboxylic Acids
Solution:
This is an example of Benzil-Benzilic acid rearrangement reaction
$\overset{\ominus}{OH}$ attacks at the more reactive $(C=O)$ group, (containing more KWG or less EDG). Et is more EDG than Me (due to $+ I$ effect; here no H.C.). Therefore, $\overset{\ominus}{ OH }$ attacks $( C = O )$ with $( Me )$ group
