Answer:
2 [tex]\sigma[/tex] bonds and 2 [tex]\pi[/tex] bonds
Explanation:
If we consider the the bonding in the [tex]CO_{2}[/tex] molecule:
[tex]O = 1s^{2}\ 2s^{2}\ 2p^{4}[/tex]
[tex]C = 1s^{2}\ 2s^{2}\ 2p^{2}[/tex]
Thus carbon forms double bonds with oxygen:
O = C = O
Now,
We know that double bond comprises of a [tex]\sigma\ bond[/tex] and a [tex]\pi \ bond[/tex]
Since, in the [tex]CO_{2}[/tex], there are 2 double bonds thus there are 2 [tex]\sigma[/tex] bonds and 2 [tex]\pi[/tex] bonds in the molecules.
