Question

write the mechanism of CARBOHYDRINE FORMATION when Carbonyl compound reacts with HCN in the presence of alkali.​

Answer 1

Simple carbonyl compounds and Formaldehyde react quickly with HCN to create the cyanohydrin compounds.

• The compounds are created in an aqueous solution.
• The cyanohydrins greatly accelerate HCN oligomeri-zation levels, both in a homogeneous solution and in the frozen state.
• The mechanism followed is - HCN + OH →→ CN + H2O
• Nucleophile ( CN) → Tetrahedral Intermediate → H+ ( Cyanohydrin)
