Title: Does carbon monoxide have charge?
Post by: mir on March 21, 2006, 05:37:08 AM

I have seen represenations of carbon monoxide with a tripplebond with a positive charge og oxygen and a negative charge on carbon...

But this representation assume that carbon is in the same oxidation state as in organic molecules... Or is this right?

charge seperation occurs because one of the bond in the C=O is actually a dative bond, whereby oxygen donated an electron pair to form a covalent bond between carbon and oxygen. Since oxygen "looses" its electron, it gains a positive charge and since carbon "gains" an additional electron pair, it gains a negative charge. The overall charge is zero.

According to the experiementally result, the CO is very week polarized molecule. So charges on Cand O is very little
