bond polarity and dipole moment

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..

The measurement of dipole moment helps in distinguishing between polar and non-polar molecules. Non-polar molecules have zero dipole moment while polar molecules have some value of dipole moment. For e..

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

When the atoms forming bonds are different, the electron attracting powers of the two atoms in a bond may differ. Then, the shared pair will be displaced towards the atom having more electronegativity. For example, in a moleclule of HCl, the electronegativities of Cl and H are ..

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..

Electric Dipole - It is a pair of point charges with equal magnitude and opposite in sign separated by a distance. Many physical systems from molecules to TV antenna can be described as electric dipoles. A water molecule is an example of an electric dipole. Even though..

Polarity in Covalent Bonds - Two types of covalent bonds are formed depending upon the electronegativity of the combining elemen..

Non-polar covalent bond When a covalent bond is formed between two atoms of the same element, the shared electron pair will lie exactly midway between the two atoms i.e. the electrons are equally shared by the atoms. The resulting molecule will be electrically symm..
