Question

The bond order of H, and He2 is.​

Answer 1

Answer:

Hydrogen and Two molecules of Helium

Answer 2

Answer:

Correct option is

A

0.5, one unpaired electron

Species He2+ has 3 electrons.

MO Electronic Configuration is = σ1s2σ∗1s1, 

Bonding electrons = 2 and  antibonding electrons = 1 

Bondorder=22−1=21

Since an unpaired electron is present. So,  it is paramagnetic.

So, the correct option is A
