Q. Choose the incorrect statement
A) Carboxylic acids have higher boiling points than those of alcohols of similar molecular weight
B) Carboxylic acids have lower boiling points than those of alcohols of similar molecular weight
C) Carboxylic acids $(C_{1}\ to\ C_{4})$ are soluble in water
D) The melting points of carboxylic acids increase or decrease in an irregular manner
Explanation
(b)
As compared to alcohol, the $O - H$ bond in carboxylic acids is more strongly polarised due to the adjacent electron withdrawing carbonyl group. Therefore carboxylic acid from stronger intermolecular H-bonds than alcohols, and the boiling points of carboxylic acids are much higher than those of alcohol of comparable molecular masses
