Alkyl halide undergoes sequence of reaction to form primary amine. Identify X and Y in the following sequence
`C_2H_5Broverset(X) rarr"Product " overset(Y)rarrC_3H_7NH_2`

Options

A. `X=KCN,Y=LiAlH_4`
B. `X=KCN,Y=H_3O^(+)`
C. `X=CH_3Cl,Y=AlCl_3//HCl`
D. `X=CH_3NH_2,Y=HNO_2`

Answer

A

Explanation

`C_2H_5Br overset(KCN(X))(rarr)C_2H_5CN overset(LiAlH_4(Y))(rarr)C_2H_5CH_2NH_2(C_3H_7NH_2)`
X=KCN,Y=`LiAlH_4`
