Question

Assertion (A): Sodium metal is stored in kerosene

Reason (R): The density of sodium is less than water

• A. A and R are true & R is the correct explanation of A
• B. A and R are true but the R is not the correct explanation of A
• C. A is true, R is false
• D. A is false, R is true

Answer 1

The correct option is B

A and R are true but the R is not the correct explanation of A

Sodium is stored under kerosene because it does not react with kerosene. On the other hand, Sodium violently reacts with water.

Taken one by one - both the assertion and reason are true but the reason does not explain the assertion.
