Choose the correct statement (s) -
A
The formation of α -hydroxynitrile from aldehyde and ketone is usually a reversible process.
B
The formation of α -hydroxynitrile is catalysed by OH – . The use of H + decreases the nucleophilicity (HCN 
H + + CN – )
H + + CN – )
C
Acrolein (CH 2 =CH–CH=O) on treatment with HCN/OH – do not give α -hydroxy nitrile (cyanohydrin)
D
Benzaldehyde on treatment with HCN/OH – give optically active cyanohydrin molecule.
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(a, b, d) The use of H + decreases nucleophilicity but increases electrophilicity. HCN/OH – gives 1,2-adition.
