CO2 has 2 oxygen atoms bonded with double bonds to the Carbon. That makes the molecule a straight line with an Oat each end. Since the ends are the same there is no dipole.

CO has an O at one end and a C at the other end. The O end is more electronegative than the C end, so the O end has a partial - charge and the C end has a partial + charge, making a dipole

SO3 is a non polar molecule.

Although the bonds between the S and O atoms are polar because S is more electronegative than O hence creating an electronegativity difference, the molecule is non polar. This is because the negative and positive centres are both loacted in the same place (at the S molecule) as they are all on the same plane and therefore there is no permanant dipole as the dipoles in the bond cancel each other out, therefore the molecule is non polar.

O=C=O

The molecule is linear and symmetric. Hence the individual dipole moments of C-O cancel each other.

Why does CO2 have a permanent dipole-dipole interaction?

Carbonate (CO3 2-) is trigonal planar with a central C and three O's 120 degrees from each other (D3h symmetry). All the O's have the same electron density because of resonance. This gives carbonate no dipole.


Why dipole moment is zero in non polar molecules non zero in polar molecules?

The dipole moment is zero in nonpolar molecules and non-zero in polar molecules due to electronegativity. Polar molecules have balanced electronegativity that will cancel one another out, while nonpolar molecules have unbalanced electronegativity causing dipole moments.

What molecule has zero dipole moment?

Carbon dioxide has a zero dipole moment. The C=O bonds are polar, but because the molecule is linear, the polarities cancel one another and the molecule has a zero dipole moment. Click on the related link for an illustration of the carbon dioxide molecule showing its dipole moment.
