measure 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 coincide with t..

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 covalent mole..

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..

is known as the torque of the applied force about an axis which passes through O and is perpendicular to the X-Y plane. The torque measures the turning or twisting effect of force. The torque is called as the moment of force. Expression for force can be written in terms of an..

>If the coil has N turns then where p m = NIA is called the magnetic dipole moment of the lo..

On comparing the two-field pattern, the current carrying solenoid from outside resembles a bar magnet. Inside the solenoid there is a strong magnetic field, which can magnetise a specimen. Solenoid is hollow from inside whereas the bar magnet is solid. Here we note the close similarity between the..

In polyatomic molecules the dipole moment not only depends upon the individual dipole moments of the bonds but also on the spatial arrangement of the various bonds in the molecule. In such molecules the dipole moment of the molecule is th..

Oxygen is more electronegative than hydrogen, being only second to fluorine in its electronegativity. Its high electronegativity causes the oxygen atom to pull the shared pairs of electrons more towards itself. As a result, the O-H bond acquires polarity. Since the two O-H bonds in water are incli..
