Question

What will be the correct order of vapour pressure of water, acetone and ether at ${30}^0$C. Given that among these compounds, water has maximum boiling point and ether has minimum boiling point.

• A. Water < Ether < Acetone
• B. Water < Acetone < Ether
• C. Ether < Acetone < Water
• D. Acetone < Ether < Water

Answer 1

Answer: (B)

Water < Acetone < Ether

Higher the boiling point lower will be the vapour pressure. Thus, the correct order of vapour pressure is Water < Acetone < Ether.
