The ammonia has a molecular formula NH₃, and it is a polar molecule. This is because of NH₃ molecules have asymmetrical charge distributions.
Ammonia(NH₃) molecule is a polar because it has asymmetrical or uneven distribution of a charge. The electronegativity of nitrogen in ammonia is higher than the hydrogen, which causes the asymmetrical distribution of charge. Due to this, the molecule is electrically polarized.
A polar molecule is defined as a molecule which contains net positive or negative charge due to unequal sharing of electrons, while non-polar molecules does not show unequal sharing of electrons. Polar molecules are highly attracted to the water. The electrons in a polar molecule is highly concentrated in one region than the other region of the molecule.
Therefore, NH₃ molecule is a polar due to the asymmetrical charge distributions.
