Statement 1:A mixture of cyclohexane and ethanol shows -ve deviation from Raoult’s law Statement 2:Cyclohexane reduces the intermolecular attraction between ethanol molecules

Question

Statement 1:A mixture of cyclohexane and ethanol shows -ve deviation from Raoult’s law Statement 2:Cyclohexane reduces the intermolecular attraction between ethanol molecules (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

The given explanation is correct and a reduction in molecular attraction will increase vaporisation nature and lead for higher vapour pressure than that calculated by Raoult’s law. Thus, mixture will show positive deviation

If both Statement 1 and Statement 2 are true and the statement 2 is the correct explanation of the statement 1

Ifboth Statement 1 and Statement 2 are true but statement 2 is not the correct explanation of the Statement 1

If Statement 1 is true but Statement 2 is false

If Statement 1 is false but Statement 2 is true

The given explanation is correct and a reduction in molecular attraction will increase vaporisation nature and lead for higher vapour pressure than that calculated by Raoult’s law. Thus, mixture will show positive deviation
