Base catalyzed aldol condensation occurs with

Options

  1. A2,2-dimethyl propanal
  2. BPropanal
  3. CBenzaldehyde
  4. D2,2-dimethyl propenal and Benzaldehyde

Correct answer

B. Propanal

Step-by-step solution

Aldol condensation is given by aldehydes and ketones that contain at least one -hydrogen atom. In 2,2-dimethyl propanal, the -carbon is attached to three methyl groups and has no -hydrogen. In benzaldehyde, the -carbon is part of the benzene ring and has no -hydrogen. In propanal ( CH₃-CH₂-CHO ), the -carbon has two -hydrogen atoms. Therefore, it undergoes base-catalyzed aldol condensation. Answer: Propanal
