Which of the following correctly describes the dipole moments () of Acetaldehyde and Acetone? — Aldehydes Ketones and Carboxylic Acids Chemistry Question

💡 Solution & Explanation

Alkyl groups exert an electron-donating (+I) effect. Acetone has two methyl groups pushing electron density toward the carbonyl carbon, polarizing the $C=O$ bond more than the single methyl group in acetaldehyde.
