Select correct statement (s) :

A.Carboxylic acids have higher boiling points than

C.The presence of carbonyl group in acid derivative

D.All of the above statements are correct✓ Correct

Explanation

The boiling point of carboxylic acid is higher than the boiling point of the esters due to the intermolecular H-bonding which leads to dimer formation. Hydrogen bonding is present between the molecules in which the hydrogen atom is bonded to very electronegative atom such as N, O etc. The carbonyl group is one of the reason why the acid derivatives are polar. Hence the correct answer is option (d)
