Assertion: Branched polymers have higher tensile strength than linear polymers.
Reason: The intermolecular force of attraction in linear polymer is more than that in branched polymers.
Reason: The intermolecular force of attraction in linear polymer is more than that in branched polymers.
View answer and explanation
Correct option: D
Assertion is wrong, but reason is correct statement.
