# When carbon and oxygen bond, the molecule contains how many pairs of bonding electrons?

Aug 24, 2017

Well, it might contain three pairs of bonding electrons....

#### Explanation:

In carbon monoxide, ""^(-):C-=O^+; clearly there are three bonding pairs.....

In carbon dioxide, $O = C = O$; there are four bonding pairs....

There is also carbon suboxide, $O = C = C = C = O$, there are eight bonding pairs....not that you could put this molecule in a bottle.

And in ethers, $R - O - R$, there are 2 bonding pairs....
