Assertion (A): The molecular mass of polymers cannot be calculated using the boiling point or freezing point method.
Reason (R ): The boiling point method for determining the molecular masses is used for compounds stable at high temperature.

Options

A. Statement-1 is True, Statement-2 is True, Statement -2 is correct explanation for Statement -1
B. Statement-1 is True, Statement-2 is True, Statement-2 is NOT a correct explanation for Statement-1
C. Statement-1 is True, Statement-2 is False
D. Statement-1 is False, Statement-2 is True

Explanation

Learn as a fact. Molecular masses of large molecules is determined using Osmotic pressure technique. Molecular mass of smaller molecules is determined using freezing point lowering method.
