1)

 Identify compound 'B' in following series of reactions?

 Acetonitrile    Na/alcohol  A  NaNo2/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]

CH3CN   Na/alcohol CH3CH2NH2

 Acetonitrile                               Ethyl amine [A]

NaNO2/dil.HCl            CH3CH2OH

                                Ethyl Alcohol

                                       [B]
