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.A. If both `(A)` and `(R )` are correct, and `(R )` is the correct explanation of `(A)`.B. If both `(A)` and `(R )` are correct, but `(R )` is not the correct explanation of `(A)`.C. If `(A)` is correct, but `(R )` is incorrect.D. If `(A)` is correct, but `(R )` is correct. |
