Practice mode Aldehydes and Ketones

Why are aldehydes generally more reactive than ketones towards nucleophilic addition?

Correct answer A. Aldehydes have less steric hindrance and fewer electron-donating alkyl groups

Explanation

In ketones two alkyl groups crowd the carbonyl carbon and push electron density onto it, reducing its partial positive charge. Aldehydes have only one or no alkyl group, so nucleophiles attack them more easily.
