Assertion (A): The value of van der Waals' constant '' is higher for ammonia than for nitrogen.
Reason (R): Intermolecular hydrogen bonding is present in ammonia.
Reason (R): Intermolecular hydrogen bonding is present in ammonia.
View answer and explanation
Correct option: A
Assertion is correct, reason is correct; reason is a correct explanation for assertion
Option A is correct. The van der Waals constant 'a' reflects the strength of intermolecular forces, and ammonia exhibits hydrogen bonding, which is a stronger intermolecular force than the London dispersion forces present in nitrogen.
