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 ?

Options

A. Water `lt` ether `lt` acetone
B. Water `lt` acetone `lt` ether
C. Ether `lt` acetone `lt` water
D. Acetone `lt` ether `lt` water

Answer

B

Explanation

The given compounds are
`underset(("Maximum b.p"))("Water")", acetone,"underset(("Minimum b.p."))("ether")`
Greater the boiling point, lower is the vapour pressure of the solvent. Hence, the correct order of vapour pressure will be
Water `lt` acetone `lt` ether
