Aromatic aldehydes undergo disproportionation in the presence of concentrated sodium or potassium hydroxide to give the corresponding alcohol and acid salt. This reaction is known as:

The reaction $Ph-CDO \xrightarrow{50\% \text{ aq. } NaOH, \text{ warm}} Ph-COO^- + \text{an alcohol}$. This alcohol is:

The product $(B)$ in the given reaction is:

The enol form of acetone,after treatment with $D_2O$,gives:

The reaction of cyclohexanone with $NaOH$ followed by heating $(\Delta)$ gives product $(A)$. Identify $(A)$.

An organic compound $CH_3-CH=CH-CH_2-CHO$ is taken in two different containers $A$ and $B$. Sample in $A$ is treated with $H_2 / Ni$ forming new compound $P$. Sample in $B$ is treated with $LiAlH_4$ and hydrolyzed further forming new compound $Q$. Identify $P$ and $Q$.
