A

shows a negative deviation from Raoult's law

B

shows a positive deviation from Raoult's law

C

behaves like a near ideal solution

D

obeys Raoult's law

Text Solution

Verified by Experts

The correct Answer is:
B
A solution of acetone in ethanol shows a positive deviation from Raoult's lawdue to miscibility of these two liquids with difference of polarity and length of hydrocarbon chain.
