Question

Explain the molecular orbital structure, bond order, stability and magnetic behavior of Hydrogen molecule on the basis of molecular orbital theory.

Open in App

Solution

Molecular orbital structure of $H_{2}$ is.
Bond order $= \frac{B o n d i n g e l e c t r o n s - (n o n - b o n d i n g e l e c t r o n s)}{2}$
$= \frac{2 - 0}{2} = 1 \Rightarrow$ Bond order.
There is no unpaired electrons in $H_{2}$ . So, the $H_{2}$ molecule is stable and Diamagnetic.
