Questions & Step-by-Step Solutions

Which of the following statements is true regarding the boiling points of aldehydes and ketones? (2023)
  • Step 1: Understand what aldehydes and ketones are. Aldehydes have a carbonyl group (C=O) at the end of the carbon chain, while ketones have a carbonyl group in the middle of the carbon chain.
  • Step 2: Know that both aldehydes and ketones can form dipole-dipole interactions because of the polar carbonyl group.
  • Step 3: Recognize that the strength of dipole-dipole interactions affects boiling points. Stronger interactions lead to higher boiling points.
  • Step 4: Compare the structure of aldehydes and ketones. Ketones have more alkyl groups around the carbonyl group, which can stabilize the molecule and enhance dipole-dipole interactions.
  • Step 5: Conclude that because ketones have stronger dipole-dipole interactions than aldehydes, they generally have higher boiling points.
