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

(1) Water<ether<acetone

(2) Water<acetone<ether

(3) Ether<acetone<water

(4) Acetone<ether<water

HINT-magnitude of vapour pressure and boiling point are inversely related

EXPLAINATION(2) The given compounds are
Greater the boiling point, lower is the vapour pressure of the solvent. Hence, the correct order of vapour pressure will be
Water<acetone<ether.
