Question

Does ${\mathrm{CO}}_2$ have double bond ?

Answer 1

The formation of the double bond in ${\mathrm{CO}}_2$ is explained below:

1. Yes, the molecule of ${\mathrm{CO}}_2$ contains two double bonds.
2. The formation of a double bond occurs when $2$ pairs of electrons are shared between two atoms to attain maximum stability.
3. According to the Lewis structure, a carbon contributes its four electrons and each oxygen atom contributes its two electrons to form a stable molecule where four pairs of electrons are available.

Thus, there are two double bond present in ${\mathrm{CO}}_2$.
