Question

Describe the bonding in $H_2$?

• A. s-s bonds
• B. s-p bonds
• C. p-p bonds
• D. ${sp}^3-p$ bonds
• E. ${sp}^2-{sp}^2$ bonds

Answer 1

The correct option is A s-s bonds

The electronic configuration of the hydrogen atom is $1s^1$.

Therefore, $H_2$ molecule contain $S-S$ overlap.

Therefore, the bonding in $H_2$ is $S-S$ sigma bond.
