Question

Nitrogen (N) is much more electronegative than hydrogen (H). Knowing this, consider how the electrons will be shared in ammonia (NH3). What do you predict about the polarity of ammonia

Answer 1

Answer:

Ammonia is a polar molecule

Explanation:

Nitrogen is more electronegative than hydrogen, so it's ability to attract electrons is higher.

This means that shared electrons would be mostly pulled towards the central nitrogen atom.

It is a polar molecule because it has an asymmetrical shape, and unequal charges. Nitrogen has lone pair, and lone pair-bonding pair repel second most (after lone pair-lone pair), this contributes to its polarity

You should also note, that hydrogen bonded with either nitrogen, oxygen or fluorine has the most strongest bond called hydrogen bonding.

Hope this helps!
