The product formed in aldol condensation is:

  1. A
    a beta-hydroxy acid
  2. B
    a beta-hydroxy aldehyde or a beta-hydroxy ketone
  3. C
    an alpha-hydroxy aldehyde or ketone.
  4. D
    an alpha, beta-unsaturated ester

Solution & Step-by-step Explanation

Aldol condensation involves the reaction of an aldehyde or ketone having at least one -hydrogen with dilute alkali. The initial product is a -hydroxy aldehyde (aldol) or a -hydroxy ketone (ketol). Upon heating, these undergo dehydration to form -unsaturated carbonyl compounds.
