$C {O}_{2}$ molecule has a linear shape .

#### Explanation:

In order to predict the shape and molecular geometry of molecules, we will need to draw their Lewis structures.

The Lewis structure for carbon dioxide is represented in this figure:

As represented in the figure above, the shape of the molecule $C {O}_{2}$ is Linear.

Let us consider another example: $N {O}_{2}$.

The Lewis structure of nitrogen dioxide is represented in this figure:

As represented in the figure above, the shape of the molecule $N {O}_{2}$ is Bent.

The lone pair on nitrogen will push the two $N - O$ bonds away of it, because of the repulsion of their electrons.
