How does steric hindrance affect the reactivity of aldehydes and ketones in nucleophilic addition reactions?

Options

  1. AIt increases reactivity in aldehydes and ketones
  2. BIt decreases reactivity in aldehydes and ketones
  3. CIt has no effect on reactivity
  4. DIt reverses the reactivity

Correct answer

B. It decreases reactivity in aldehydes and ketones

Step-by-step solution

Sterically, the presence of two relatively large substituents in ketones hinders the approach of a nucleophile to the carbonyl carbon, reducing their reactivity compared to aldehydes.
