• A. All aldehydes are insoluble in benzene
• B. Higher aldehydes are more fragrant
• C. $n$-Butane has more boiling point than acetone
• D. Methanal and propanone are immiscible with water in all proportions

Answer 1

Answer: (B)

Higher Aldehydes are soluble ib Benzene.
lower Aldehydea are pungent but higher Aldehydes are fragrant.
acetone is more polar than n-Butane and weight is comparable ,
so acetone has higher boiling point.
Methanal is soluble in water.
