• B. Aldehydes and ketones have higher boiling points than alcohols and carboxylic acids of comparable molecular masses.
• C. Aldehydes and ketones have lower boiling points than alcohols but higher boiling points than carboxylic acids of comparable molecular masses.
• D. Aldehydes and ketones have higher boiling points than alcohols but lower boiling points than carboxylic acids of comparable molecular masses.

Answer 1
