The product formed in aldol condensation is:

Options

  1. Aa-beta hydroxy aldehyde or a betahydroxy ketone
  2. Ban alpha-hydroxy aldehyde or ketone
  3. Can alpha, beta unsaturated ester
  4. Da beta-hydroxy acid

Correct answer

A. a-beta hydroxy aldehyde or a betahydroxy ketone

Step-by-step solution

Aldehydes and ketones having at least one -hydrogen atom in presence of dilute alkali give -hydroxy aldehyde or -hydroxy ketone. Caution Those aldehydes which does not have -hydrogen atom like HCHO , does not give aldol condensation reaction.
