Explain the formation of $H_{2}$ molecule on the basis of valence bond theory.

Open in App

Solution

The elecronic confguration of hydrogen is $1 s^{1}$ .

Thus, it contains one unpaired electron in 1s orbital.

Two H atoms, each having one unpaired electron, combine and share their electron to form a covalent bond in which two electrons are paired.

$H \cdot + H \cdot \to H \cdot \cdot H$
