Vedclass · Answer

(A) The reaction sequence is as follows:$1$. $CH_3CH_2Br + KCN \rightarrow CH_3CH_2CN (A) + KBr$$2$. $CH_3CH_2CN + 4[H] \xrightarrow{LiAlH_4} CH_3CH_2CH_2NH_2 (B)$$3$. $CH_3CH_2CH_2NH_2 + HNO_2$ $\xrightarrow{0^{\circ}C} [CH_3CH_2CH_2N_2^+]$ $\rightarrow CH_3CH_2CH_2^+$ $\xrightarrow{H_2O} CH_3CH_2CH_2OH (C)$(Note: While rearrangement to the more stable isopropyl carbocation can occur,the primary alcohol $CH_3CH_2CH_2OH$ is the major product expected in this context.)

Identify $A$,$B$ and $C$ in the sequence: $CH_3CH_2Br$ $\xrightarrow[Alc.]{KCN} A$ $\xrightarrow{LiAlH_4} B$ $\xrightarrow[0^{\circ}C]{HNO_2} C$
