Statement 1: Ebullioscopy or cryoscopy cannot be used for the determination of molar mass of polymers Statement 2: High molar mass solute leads to very low value of Δ Tb or Δ Tf

Question

Statement 1: Ebullioscopy or cryoscopy cannot be used for the determination of molar mass of polymers Statement 2: High molar mass solute leads to very low value of Δ Tb or Δ Tf (A) If both Statement 1 and Statement 2 are true and the statement 2 is the correct explanation of the statement 1 (B) Ifboth Statement 1 and Statement 2 are true but statement 2 is not the correct explanation of the Statement 1 (C) If Statement 1 is true but Statement 2 is false (D) If Statement 1 is false but Statement 2 is true

If molar mass is low, Δ Tb or Δ Tf being low cannot be read out accurately. A little error in measurement of Δ Tb will cause abnormal values of mol. wt

Q. Statement 1: Ebullioscopy or cryoscopy cannot be used for the determination of molar mass of polymers
Statement 2: High molar mass solute leads to very low value of $Δ T_{b}$ or $Δ T_{f}$
