A dipole moment is defined as the mathematical product of the separation of the ends of a dipole and the magnitude of the charges. Dipole moments are created by the separation of charge over a molecule. Some common molecules with dipoles are H2O, HF, NH3, etc...
Electric dipole in the polar molecules in which the centre of positive charge does not coincide with the centre of negative charge is called polar dipole.
And,the behavior of a dipole that is described by a vector p that is p = q x 2a is called dipole moment.

NH3 is not symmetrical.So it has a dipole moment
NH3 is an asymmetrical compound.So it is exhibits.
no dipole moment
what is dipole moment of 1,1-Dibromoethene
N2O has a dipole moment of 0.166 D
NH3 is not symmetrical.So it has a dipole moment
NH3 is an asymmetrical compound.So it is exhibits.
The dipole moment of Glucose is 1.8
no dipole moment
what is dipole moment of 1,1-Dibromoethene
N2O has a dipole moment of 0.166 D
KrF2 is a linear molecule and therefore there is no dipole moment.
because dipole moment depends upon charge i.e. electronegativity as per the formula of dipole moment
NH3 is polar compound.So dipole moment is not zero.
It is a symmetrical tetrahedral molecule so has zero dipole moment.
dipole moment of water is 1.85 Debye
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.
