17. What will be the correct order of vapour pressure of water, acetone and ether at 30°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
Water(Maximum b p), acetone, ether(Minimum b p)
Greater the boiling point, lower is the vapour pressure of the solvent. Hence, the correct order of vapour pressure will be
Water<acetone<ether.
