Q24 / 160 · TS EAMCET 2019 (04 May Shift 2) · Chemistry

If a solute associates in a solvent, its experimentally calculated molar mass using boiling point elevation method will be

A
half of the actual value
B
will remain same as actual value
C
one fourth of the actual value
Correct answer
D
higher than the actual value

Solution

If a solute associates in a solvent, its experimentally calculated molar mass using boiling point elevation method will be higher than the actual value. As colligative property are inversely proportional to molecular mass of solute.

Hence, the correct answer is option: 'D'.
