Whta's the dipole moment of CO?
« on: October 09, 2004, 03:27:13 AM »

C is triple bonds bonded to O, and one of the bond is dative covalent bond which the pair of e- is contributed to C from O. So, the carbon is carried a negative cahrge and oxygen is carried postive charge, right?

How about writing the dipole moment of CO? Due to the electronegativity, O is patial negative while C is patial postive. Therefore, is it not correct to write this dipole moment for CO?

So, what is the right expression of the charge for CO?

You write dipole moments when their is a diffence in charge. And always from the positive pointing to the negative.

Most Common Suggestions I Make on the Forums.
1. Always start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex

How about the charge?

carbon is partial negatively charged
so the dipole moment directs from oxygen to carbon.

If someone thinks O is more electronegative, so that the dipole moment points from C to O, it is wrong, right?

I want to make it more clear that the dipole moment is complete or partial?
Actually, the pair of e- of the 2nd pi bond is donated by the lone pair of O.

i tink the electrons donated by O are still shared by O and C. Therefore the correct dipole moment should be still based on electronegetivity which means arrows points from C to O..yea...
