Vedclass · Answer

(A) Acetone reacts with $HCN$ (generated from $NaCN/HCl$) to form acetone cyanohydrin $(A)$ through nucleophilic addition.Subsequent acidic hydrolysis of the nitrile group $(-CN)$ in $A$ with heat $(\Delta)$ yields $2$-hydroxy-$2$-methylpropanoic acid $(B)$.$CH_3-CO-CH_3 + HCN$ $\rightarrow CH_3-C(OH)(CN)-CH_3 (A)$ $\xrightarrow{H_3O^{+}/\Delta} CH_3-C(OH)(COOH)-CH_3 (B)$.

$CH_3-CO-CH_3$ $\xrightarrow{NaCN/HCl} A$ $\xrightarrow{H_3O^{+}/\Delta} B$. In the above sequence of reactions,$A$ and $B$ are:
