Text Solution

Verified by Experts

The correct Answer is:
A
Only those compounds which have ` alpha ` - H give Aldol condensation
(a) ` Cl _3 overset (alpha ) C overset (O ) overset ("||")C H `
(b) ` C _ 6 H _ 5 overset (alpha ) C H _2 CHO `
` ("no " alpha - H ) " " (alpha - H ) `
(c ) ` underset("(" alpha - H")") C _ 4 H _ 9 overset ( alpha ) CH _ 2 CHO `
(d) `CH _ 3 NO _ 2 `
