Question

at a particular temp why vapour pressure of acetone is less than that of ether?

Answer 1

at a particular temperature vapour pressure of acetone is less than that of either because Ether is highly inflammable

Answer 2

● Answer -
At a particular temp vapour pressure of acetone is less than that of ether because intermolecular forces of attraction are stronger in acetone than that in ether.

● Explaination -
- Acetone has hydrogen bonding. Thud intermolecular forces of attraction between molecules of acetone are stronger.
- This makes boiling point of acetone higher than ether.
- Boiling point is inversely proportional to vapour pressure.
- Thus acetone has vapour pressure lesser than ether.
