Each question contains STATEMENT-I(Assertion) and STATEMENT-2(Reason).the statement carefully and mark the correct answer according to the instruction given below:
STATEMENT - 1 : The molecular mass of acetic acid determined by depression in freezing point method in benzene and water was found to be differrent.
STATEMENT - 2 : Water is polar and benzene is non-polar.

A

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

B

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

C

If assertion is true but reason is false

D

If both assertion and reason are false

Text Solution

Verified by Experts

The correct Answer is:
A
Depression in freeizng point is a colligative property which depends upon the number of particles. The number of particles are different in case of benzene and waer that is why molecular weight of acetic acid determined by depression in freezing point method is also different.
