Question

Discribe dipole moment & give the example.

Answer 1

A dipole moment is simply the measure of net polarity in a molecule. If a molecule contains polar bonds that are unevenly distributed about the center, there will be an uneven charge distribution across the entire molecule, making it a polar molecule. Polar molecules exhibit a large difference in electrical charge (a positive end and a negative end), otherwise known as a dipole moment.
For example, ammonia (NHsub3) is a polar molecule. As you can see, ammonia consists of one nitrogen atom covalently bonded to three hydrogen atoms. Since nitrogen has a stronger attraction for electrons than hydrogen, the electrons that they share are drawn towards nitrogen and away from hydrogen. This gives nitrogen a partial negative charge (which is denoted by by a minus sign on N) and hydrogen a partial positive charge (which is denoted by a plus sign on each H). The presence of both a positive and negative charge on the molecule means that ammonia is polar and, therefore, exhibits a net dipole moment.....
I hope this may help u

Answer 2

dipole moment is a measurement of the sepration of two electrical charges &dipole momet is vector quantity.The magnitude is equal to the charge multipled by the distance between the charges and the direction is from negative charge to positive charge.
