Polarity of a molecule is determined by

difference in electronegativity value and size

difference in electronegativity value and charges

Why is the molecule nonpolar?

There are no lone pairs on the central atom and all of the atoms bonded to the central atom are the same.

There are lone pairs on the central atom.

There are different types of elements bonded to the central atom.

Why is the molecule polar?

There is a lone pair on the central atom and a high electronegative nitrogen pulling the electrons.

There are different types of elements bonded to the central atom.

The electronegativities of the hydrogens pull the electrons away from the nitrogen.

Why is the molecule polar?

The shape is bent and there are are lone pairs on the central atom.

There are different types of elements bonded to the central atom.

Why is the molecule polar?
