Vedclass · Answer

(A) $1$. The reaction of butan$-2-$one $(CH_3-CH_2-CO-CH_3)$ with $CN^-$ (cyanide ion) is a nucleophilic addition reaction,which forms a cyanohydrin intermediate $(G)$: $CH_3-CH_2-C(OH)(CN)-CH_3$.$2$. Treatment of the cyanohydrin $(G)$ with concentrated $95\% \ H_2SO_4$ and heat leads to two simultaneous processes: hydrolysis of the nitrile $(-CN)$ group to a carboxylic acid $(-COOH)$ group and dehydration of the alcohol $(-OH)$ group to form a double bond.$3$. The dehydration follows $Saytzeff$ rule,forming the more substituted alkene. The resulting product $H$ is $CH_3-CH=C(CH_3)-COOH$ ($2$-methylbut$-2-$enoic acid).

The major product $H$ in the given reaction sequence is:
$CH_3-CH_2-CO-CH_3$ $\xrightarrow{CN^-} G$ $\xrightarrow{95\% \ H_2SO_4, \Delta} H$
