Assertion: A mixture of cyclohexane and ...

Assertion: A mixture of cyclohexane and ethanol shows -ve deviation from Raoult's law.
Reason:Cyclohexane reduces the intermolecular attraction between ethanol molecules.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion

B

If both the assertion and reason are true but reason is not the correct explanation of the assertion

C

If assertion is true but reason is false

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
D
The given explaination is correct and a reduction in molecular attraction will increase vaporisation nature and lead for higher vapour prssure than that calculated by Raoult's law .Thus ,mixture will shows positive deviation.
