what is the dipole moment of carbon monoxide? is the dipole
moment of carbon dioxide zero?

Hi,
The dipole moment of CO is about 0 112 D It is not zero but is
very less C is triply bonded to O O is more electronegative than C
and so the molecule is polar with a slight negative charge at the O
end and a slight positive charge at the C end When the electron
pair is donated to C by O via the coordinate bond, the partial
negative charge on O decreases and that of carbon increases which
result in lower difference of effective electronegativity between
the atoms in the compound which in turn suppresses the dipole
moment This is the reason for the lower dipole moment of CO
Hope this helps
Good luck!
