dipole moment and polarity

Dipole Moment - A Measure of Degree of Polarity - Molecules having two equal and opposite charges separated by certain distance are said to possess an electric dipole. In the case of such polar molecules, the centre of negative charge does not coinc..

Molecules having two equal and opposite charges separated by certain distance are said to possess an electric dipole. In the case of such polar molecules, the centre of negative charge does not coincide with the centre of positive charge. The extent of polarity in such..

Dipole moment plays very important role in understanding the nature of chemical bond..

The Bohr's atom model pictures the electrons to revolve around stationary heavy nucleus of change +ze. The moving electron constitutes a current where e is the electronic charge and T the time period of revolution. Also where v is its orbital velocity and the radius of the orbit. The small mag..

These are the interparticle forces among the polar molecules. These forces arise due to electrostatic interactions between the oppositely charged ends of permanent dipoles. The positive end of one molecule attracts the negative end of the other molecule and vice versa as shown i..

The ordinary magnetic effects in materials are determined by atomic magnetism. On continuing to cut a magnet into its smallest bit, we reach the level of a single atom. This is a tiny current loop in which the current corresponds to the circulation of the electrons in the atom. To this atomic curr..

A diatomic molecule has two atoms bonded to each other by a covalent bond. In such a molecule, the dipole moment of the bond gives the dipole moment of the molecule. Thus, a diatomic molecule is polar if the bond formed between the atoms is po..

Insulators do not conduct electricity because the electrons present in them are held tightly to the individual atoms or ions and are not free to move. However when electric field is applied polarization takes place because the nucleus is attracted towards cathode and electron cloud toward..
