JEE MAIN - Chemistry (2022 - 25th June Evening Shift - No. 9)
Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : A mixture contains benzoic acid and napthalene. The pure benzoic acid can be separated out by the use of benzene.
Reason R : Benzoic acid is soluble in hot water.
In the light of the above statements, choose the most appropriate answer from the options given below.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is NOT the correct explanation of A.
A is true but R is false.
A is false but R is true.
Explanation
Since, both benzoic acid and naphthalene will
dissolve in benzene. Hence assertion is wrong.
Benzoic acid is almost insoluble in cold water but soluble in hot water. Hence Reason is true.
Benzoic acid is almost insoluble in cold water but soluble in hot water. Hence Reason is true.
