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