The dipole moment of a molecule can be predicted by looking at the molecule's structure and the location of the dipoles within the molecule. When a molecule has no dipole moment, it will be nonpolar. A molecule with a dipole moment will be polar.
To have a dipole moment, we need to have atoms with DIFFERENT ELECTRONEGATIVITY. This is simple to explain: the atom that is more electronegative in the bond will pull, not only its own electrons tighter, but will also pull the electrons of the neighbor atom.eport Abuse. A dipole is a separation of positive and negative charge. In chemistry, it is used to refer to the distribution of positive and negative charge across a molecule. A dipole moment has a direction in space, therefore it is a vector.
