Question

Which species does not exhibits paramagnetism:

A

$N_2^+$

B

$O_2^-$

C

$CO$

D

$NO$

Answer

$CO$

Explanation

Solution

Paramagnetism arises when a species has unpaired electrons. Let's examine each of the given species:

$N_2^+$ has an unpaired electron, so it is paramagnetic.
$O_2^−$ has two unpaired electrons, making it paramagnetic.
$CO$ has all paired electrons, so it is diamagnetic (not paramagnetic).
$NO$ has an unpaired electron, so it is paramagnetic.

So, the correct option is (C): $CO$
