Question

Choose the correct statement regarding the physical properties of carbonyl compound.

• A. All aldehydes are insoluble in benzene
• B. Higher aldehydes are more fragrant
• C. n-propane has more boiling point than acetone
• D. None of the above

Answer 1

The correct option is B Higher aldehydes are more fragrant

Higher Aldehydes are soluble in Benzene.
Lower aldehydes have pungent odour but higher aldehydes have fragrant odour.
The polar and stronger carbon-to-oxygen double bond result in increase dipole-dipole interaction which causes aldehydes and ketones to have higher boiling points than those of alkanes of similar molecular masses. so n-propane has lower boiling point than acetone.
Hence, the correct option is b.
