Question

Assertion (A): $N{O}_2$ is paramagnetic molecule, whereas $N_2{O}_4$ is diamagnetic
Reason (R): Molecules with unpaired electrons are Diamagnetic.

• A. Both (A) and (R) are true and (R) is the correct explanation of (A)
• B. Both (A) and (R) are true and (R) is not the correct explanation of (A)
• C. (A) is true and (R) is false
• D. (A) is false but (R) is true

Answer 1

The correct option is C (A) is true and (R) is false

Molecules with unpaired electrons are paramagnetic
$N{O}_2$ - unpaired electron
$N_2{O}_4$ - all paired electrons
