The net dipole moment of `H_(2)O` molecule is

Assertion :- The net dipole moment of BF_3 is zero. Reason :- The net dipole moment of a molecule depends upon its geometry.

The study of dipole moment of a molecule is useful to explain the shape of a molecule and also to predict a number of other properties of the molecule. The net dipole moment of a polyatomic is the resultant of the different bond dipole moments present in that molecule. Answer the following questions on the basis of above paragraph : (i) What is dipole moment ? (ii) Out of CO_(2)and H_(2)O, which molecule is polar in nature any why ?

What is dipole moment of a molecule ?

A polar covalent bond with positive and negative charge centres at its ends is called a dipole. The polarity of a dipole is measured by its dipole moment. Mathematically it is expressed as dipole moment, mu=q xx d where q and d are the net charge and the distance between the two charges respectively. Dipole moment is a vector quantity. The net dipole moment of a polyatomic molecule is the resultant of the various bond moments present in the molecule. The values of dipole moment are expressed in Debye (D) or in SI units in terms of coulomb- metre (Cm). One of the most important applications of dipole moment is in the determination of geometry and shape of molecules besides prediction of a number of properties of the molecules. Which of the following has net dipole moment?
