Chemistry
Assertion (A): Benzene acts as non-electrolyte.
Reason (R): Benzene does not have free ions.
- 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.
Answer
Both A and R are true and R is the correct explanation of A.
Explanation — Benzene is a non-electrolyte that does not have ions even in solution. They contain only molecule. Hence both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
