A solution of 1 molal concentration of a non volatile solute will have maximum boiling pointelevation when the solvent is

Options

A. Ethyl alcohol
B. Acetone
C. Benzene
D. Chloroform

Answer

D

Explanation

`Delta T_(b)= k_(b) m, Delta T_(b)` is maximum when `k_(b)` is maximum `k_(b)` for ethanol = `1.22K kg mol^(-1)`, acetone = `1.67K kg mol^(-1)`, benzene = `2.53 K kg mol^(-1)`, chloroform `=3.63 K kg mol^(-1)`
