Cyanide ion readily adds to carbonyl group of aldehyde b. It could catalyze proton transfer C. It is a good leaving group d. Cyanide group can stabilize the carbocation intermediate formed through resonance.

Warm with 5% H2SO4 solution C. Heat with dilute NaOH d. Wash with 5% Na CO3 solution and then with 10% HCI solution
