What is dipolar nature of water?

Answer 1

A dipole refers to two electrostatic charges which are separated by distance.

In chemical compounds a dipole refers to unequal distribution of charge across a molecule that leads to an effective dipole often due to vector sum of bond dipoles.

Answer 2

Even though the total charge on a molecule is zero, the nature of chemical bonds is such that the positive and negative charges do not completely overlap in most molecules. Such molecules are said to be polar because they possess a permanentdipole moment. A good example is the dipole moment of the water molecule. Molecules with mirror symmetry like oxygen, nitrogen, carbon dioxide, and carbon tetrachloride have no permanent dipole moments. Even if there is no permanent dipole moment, it is possible to induce a dipole moment by the application of an external electric field. This is called polarization and the magnitude of the dipole moment induced is a measure of the polarizability of the molecular species.

Answer 3

A dipole something with two opposite charges separated by distance. the dipole moment is D.R wher D is the charge and R the distance.

In molecules dipoles are generally due to a difference in electronegativity between the atoms in a covalent bond causing a small negative charge on the more electronegative atom and a small positive charge on the less electronegative. A lone pair also forms a dipole, as it "sticks out" it puts more negative charge in that direction- which may reinforce the bond dipoles (as in ammonia) or oppose it as in NF3 Note that bond dipoles may cancel each other out as in CO2 (linear), CCl4 (tetrahedral) as they all go in "opposite" directions (think vectors, dipoles are vectors)

Water has a dipole moment because the bonds are polar (O is more electronegative than H) and the lone pair dipoles reinforce the bond dipoles.

Answer 4

Dipole nature means that the overall polarity of the water molecule creates a region of positive charge and region of negative charge.
