How do electron-donating alkyl groups affect the electrophilicity of the carbonyl carbon in aldehydes and ketones?

Options

  1. AThey decrease electrophilicity in aldehydes and ketones
  2. BThey increase electrophilicity in aldehydes and ketones
  3. CThey have no effect on electrophilicity
  4. DThey reverse electrophilicity

Correct answer

A. They decrease electrophilicity in aldehydes and ketones

Step-by-step solution

Electron-donating alkyl groups reduce the electrophilicity of the carbonyl carbon in aldehydes and ketones, making aldehydes more reactive than ketones.
