What is meant by Aldol?

Options

  1. AAn aldol is a type of organic acid found in citrus fruits.
  2. BAn aldol is a chemical compound with a six-membered ring structure.
  3. CWhen an aldehyde (or ketone) having at least one α-hydrogen atom undergo a reaction in the presence of dilute
  4. DAn aldol is a type of molecule with a linear carbon chain.

Correct answer

C. When an aldehyde (or ketone) having at least one α-hydrogen atom undergo a reaction in the presence of dilute

Step-by-step solution

Correct Option is : (C) When an aldehyde (or ketone) having at least one α-hydrogen atom undergo a reaction in the presence of dilute alkali as catalyst to form aldol or β-hydroxyaldehydes (or ketals in case of ketones), the reaction is called aldol condensation.
