# Why is the oxidation state of carbon in carbon monoxide +2? Why does its dipole moment point from oxygen to carbon? [duplicate]

Shouldn't it be +3 since 3 of its electrons are being pulled away by the electronegative oxygen? Also, shouldn't the dipole moment point from the carbon to the oxygen since most of the electron density in this molecule is surrounding the more electronegative oxygen?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

• It's +2 because the 3th electron pair is the non-bonding electron pair of oxygen. – Koba Mar 2 '16 at 3:39
