Is H2O polar or nonpolar?

Answer:

H2O is a polar molecule.Again,water is polar molecule because of its bent shape(V type shape) or geometry which makes the net molecular dipole moment non zero.Again,Since H2O has net molecular dipole moment,H2O is polar.

Explanation:

Here are the few steps that you help you to determine that water,H2O, is a polar molecule.

Step-1:

Draw the Lewis structure of H2O.

Step-2:

After drawing Lewis structure of H2O,now you need to consider the electronegativity difference between atoms.

Here oxygen is more electronegative than hydrogen.So,every oxygen-hydrogen bond is polar.

Step-3:

Now consider bond dipole moment.

As both oxygen and hydrogen bonds are polar,every bond has a dipole moment.

Step-4:

Now consider the geometry or shape of H2O molecule by applying VSEPR theory.

According to VSEPR theory,we get bent shape or geometry of H2O.

Step-5:

Now consider the net molecular dipole moment.

As the shape of H2O is bent(V type),one bond dipole moment does not cancel another bond's dipole moment.Thus,we get non zero value for the net molecular dipole moment .As the value of net molecular dipole moment is not zero,we can say that H2O is polar.
