Assertion (A): Natural rubber is an elastomer.

Reason (R): The intermolecular forces of attraction between the polymer chains are weak van der Walls' forces.

View answer and explanation

Correct option: A

Both A and R are correct, and R is the correct explanation of A

Option A (Both A and R are correct, and R is the correct explanation of A) is correct because natural rubber's elastomeric properties arise from the weak van der Waals forces between its polymer chains.
