 Identify compound 'B' in following series of reactions?

 Acetonitrile    $\underrightarrow{Na/alcohol}$  A  $\underrightarrow{NaNo_{2}/dil.HCl}$   B


A) Ethyl amine

B) Nitroethane

C) Ethyl alcohol

D) Ethyl chloride

Answer:

Option C

Explanation:

 In the given reaction , acetonitrile (CH3CN) on reaction with Na/alcohol  ethyl amine [A] (CH3 CH2 NH2 ) . Which on further reaction with NaNO2 /dil. HCl  followed by hydrolysis gives ethyl alcohol [B]

$CH_{3}CN$   $\underrightarrow{Na/alcohol}$ $CH_{3}CH_{2}NH_{2}$

 Acetonitrile                               Ethyl amine [A]

$\underrightarrow{NaNO_{2}/dil.HCl}$            $CH_{3}CH_{2}OH$

                                Ethyl Alcohol

                                       [B]
