Which of the following compounds will undergo self aldol condensation in the presence of cold dilute alkali?

Step-by-step solution

Aldehydes which contain -hydrogen on a saturated carbon, i.e. CH ₃ CH ₂ CHO will undergo aldol condensation. Although CH ₂= C H - CHO also contain a -hydrogen atom but cannot be easily abstracted by a base to form a carbanion and hence does not undergo aldol condensation.
