Dipole moment is the measure polarity of a polar covalent bond .
In language of physics it can be defined as the measure of strength of electric dipole. It is defined as the product magnitude of charge on the atoms and the distance between the two bonded atoms. Its common unit is debye and SI unit is coulomb metre.
The magnitude of dipole moment is equal to the product of either charge and the distance between the charges and its direction is from -q to +q.It is directed from the (-)ve charge to the (+)ve charge.In fact, it is the behavior of a dipole.
A separation of charge forming a positive and a negative end of a molecule ~APEX
It is the measure of separation of opposite charges in a molecule.
For example H2O has a negative oxygen and two positive hydrogen atoms, which gives the molecule a permanent electric dipole moment.
dipole moment can cause a slight change in the bond angle leading to change in the shape of the molecule
It is a symmetrical tetrahedral molecule so has zero dipole moment.
dipole moment of water is 1.85 Debye
The bond dipole moment measure the polarity of a chemical bond.
fluorine is symmetrical so has no dipole
Electro negativity difference is zero.So dipole moment is zero.
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.
