Question

Why is nh3 classified as a polar molecule

Answer 1

Explanation:

An ammonia $(NH_{3})$ molecule contains electronegative nitrogen atom. The difference between electronegativity of nitrogen and hydrogen atom is high.

Therefore, nitrogen will attract the shared pair of electrons more towards itself. As a result, there will be partial positive charge on hydrogen and partial negative charge on nitrogen.

Thus, due to these charges $NH_{3}$  is polar in nature.
