Solution

The correct option is B
S is wrong but E correct

Now, here our first step is to check whether statement 1 and is right.

So, let's draw MOT energy level diagram for oxygen molecule.

Eelctronic configuration of $O_{2}$ is:

$O_{2}$ $⟶$ $(σ 1 s)^{2}$ $(σ^{} 1 s)^{2}$ $(σ 2 s)^{2}$ $(σ^{} 2 s)^{2}$ $(σ 2 p_{z})^{2}$ $(π 2 p_{x^{2}} \equiv π 2 p_{y^{2}})$ $(π^{} 2 p_{x^{2}} \equiv π^{} 2 p_{y^{2}})$

Therefore, we have two unpaired electrons in $π^{} 2 p_{x}$ and $π^{} 2 p_{y}$ , therefore it will be PARAMAGNATIC.

STATEMENT I is wrong

Now,

STATEMENT II is right.

Because $O_{2}$ has two electrons in anti-bonding $π$ orbitals
