# How are the atoms arranged in the compound CO_2?

Apr 11, 2017

$\text{Carbon dioxide is linear.............}$

#### Explanation:

There are $4 \left(C\right) + 2 \times 6 \left(O\right)$ $\text{valence electrons}$ to distribute around the 3 centres. As is typical, the least electronegative atom (carbon) is placed in the middle, and thus,

$O = C = O$, from left to right there are $\text{6, 4, and 6 valence electrons}$ associated with each atom.

The central carbon is $s p - \text{hydridized}$, the oxygen atoms are $s {p}^{2} - \text{hybridized}$. The $C {O}_{2}$ molecule is thus LINEAR with $\angle O - C - O = {180}^{\circ}$.
