Why is ammonia (NH₃) classified as a polar molecule?

aleksandr82 [10.1K]

Answer:

Ammonia contains an asymmetrical distribution of electric charge.

Explanation:

Hello there!

In this case, accordingly to the electronegativity difference we can calculate for the N-H bond, and based off our periodic table, which shows an electronegativity of 3.0 and 2.1 for N and H respectively, we obtain:

$DE=3.0-2.1=0.9$

Which is within the range of polar molecule even the both of them are nonmetals. Thus, choices a and b are firstly discarded; nonetheless, even when they are both nonmetals, two of these elements usually have a nonpolar bond, which means that option C is discarded, and therefore, our answer is ammonia contains an asymmetrical distribution of electric charge.

Regards!
