Assertion : The solubility of n alcohol ...

Assertion : The solubility of n alcohol in water decreases with increase in molecular weight .
Reason : The relative proportion of the hydrocarbon part in alcohols increases with the increase in molecular weight which permits enhanced hydrogen bonding with water .

A

Statement I is true, Statement II is true, Statement II is the correct explanation of Statement I.

B

Statement I is true, Statement II is true, Statement II is not the correct explanation of Statement I.

C

Statement I is true, Statement II is false.

D

Statement I is true, Statement II is true.

Text Solution

Verified by Experts

The correct Answer is:
C
As the molecular weight increases, non-polar part increases and solubility II is incorrect because hydrogen bonding is not affected by an increase in the non-polar part.
