$H_2$

Vedclass · Answer

(B) The correct answer is $(B)$.According to Molecular Orbital Theory,the electronic configuration of $H_2$ is $(\sigma 1s)^2$.Since all electrons are paired,$H_2$ is diamagnetic in nature.In contrast,$He_2^+$ has $3$ electrons $(\sigma 1s)^2 (\sigma^* 1s)^1$,$H_2^+$ has $1$ electron $(\sigma 1s)^1$,and $H_2^-$ has $3$ electrons $(\sigma 1s)^2 (\sigma^* 1s)^1$. All these species have unpaired electrons and are therefore paramagnetic.

Which one of the following species is diamagnetic in nature?
