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.
Cl2O, Chloroethane CH3CH2Cl
Dipole moment of CO2 molecule is zero,becoz it is linear molecule,whereas SO2 is angular molecule having dipole moment 1.61 D....:)
zero because it is symmetrical molecule
NH3 is polar compound.So dipole moment is not zero.
Probably you are intending to question whether CCl4 has a dipole moment. if so the answer is no. it is because CCl4 is a symmetric molecule and hence even if each bond has a dipole moment, the algebraic sum of the dipole moments of all the four bonds cancel out resulting in zero dipole moment.
Every polar molecule has a permanent dipole.
It is a symmetrical tetrahedral molecule so has zero dipole moment.

Symmetric molecules have no dipole moment. An example is carbon tetrachloride, CCl4 , which has no dipole moment yet the C-Cl bonds are polar, (chlorine is more electronegative than carbon). The chlorine atoms each have a small negative charge but because the molecule is tetrahedral there is no dipole and therefore no dipole moment
Every polar molecule has a permanent dipole.
KrF2 is a linear molecule and therefore there is no dipole moment.
Electro negativity difference is zero.So dipole moment is zero.
Beh2 is a non polar molecule .Be and H are only shearing their electrons, there is no charge separation because the dipole moment is 0.same force is acting in each side of the Be.
This is not a naturally occuring compound. If it exists, it would not have a dipole moment as it would be a linear molecule.
dipole moment of water is 1.85 Debye
