Identify A and B in the reaction given below: Ethane nitrile → aq .H 2 SO 4 Hydrolysis A → Sodalime Decarboxylation

Step-by-step solution

Alkyl cyanides are generally named as nitriles of acids which they produce on hydrolysis. The ending ic acid of common name of the acid is replaced by term nitrile and the letter 'O' is inserted in between. For example: CH 3 − CN Acetonitrile → (H 2 O) CH 3 COOH Acetic acid So, the compound (A) is Ethanoic acid. CH 3 COOH Sodium acetate + NaOH Sodium Hydroxide → CaO Δ CH 4 Methane + Na 2 CO 3 Sodium carbonate So, the compound (B) is Methane.
