Among the following statements, choose the correct statements.

A. Boiling point of alcohols increases with an increase in the number of carbon atoms.

B. In alcohols, boiling points increase with the increase of branching in the carbon chain.

C. Boiling points of alcohols are lesser in comparison to haloalkanes of comparable molecular mass.

D. Boiling points of alcohols are higher in comparison to hydrocarbons of comparable molecular mass.

E. The high boiling points of alcohols are mainly due to the presence of intermolecular hydrogen bonding.

Alcohols have higher boiling points than other hydrocarbons with equivalent molecular weights. This is responsible for the formation of intermolecular hydrogen bonds between the hydroxyl groups of alcohol molecules. Furthermore, as the number of carbon atoms in the aliphatic carbon chain grows, the boiling point of alcohol rises. Boiling points of alcohol are generally higher when compared to other hydrocarbons having the same molecular mass. The concept behind the higher boiling point of alcohols is the presence of intermolecular hydrogen bonding between hydroxyl groups of alcohol molecules. With the increase in a carbon chain of aliphatic alcohol boiling point increases whereas with an increase in the branching of alcohol boiling point decreases.
