Assertion : NO(2) is readily dimerised ...

Assertion : `NO_(2)` is readily dimerised to `N_(2)O_(4)`
Reason :`NO_(2)` has one unpaired electron and two such electron with opposite spin in two `NO_(2)` molecules form bond between two N-atoms readily.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
a
Since the process does not require any rearrangement and thus energy of activation for dimension of `NO_(2)` is low.
