Class 10 Chemistry simulations · Carbon and its Compounds

Hydrogen bonding and boiling points of alcohols

Compare the boiling points of alcohols with alkanes of similar molecular mass and see the hydrogen bonds.

Open the simulation

What to notice

Alcohols boil much higher than alkanes of similar mass; the boiling point also rises with chain length.

Key relation

O–H···O hydrogen bonds hold alcohol molecules together

Try this

How many carbons give an alcohol boiling above 100 °C?

What you can change

• Carbon atoms in the alcohol: 1 to 4
