Describe the polarity of the molecule below and predict the shape of the molecule by looking at its lewis dot structure.

Polar and bent  

Explanation:

It looks like you are trying to find the polarity of H-O-H.

Its Lewis structure is shown in the first diagram below.

It has two lone pairs and two bonding pairs, so it is an AX₂E₂ molecule and its molecular shape is bent, as in the second diagram.

O is much more electronegative than H, so the O-H bond is highly polar. The O atom is at the negative end, and the H atom is at the positive end.

The centre of negative charge is on the O atom, and the centre of negative charge is halfway between the two H atoms, so the molecule has a net dipole pointing "up" in the picture.

Thus, H-O-H has polar bonds and is a polar molecule.
