• Time Remaining: 06:47:19

Which of the following chemical bonds is found within a molecule of ammonia, NH3, given that N is a highly electronegative element and has a valence of 5?

Nonpolar covalent bonds

Nitrogen is more electronegative than hydrogen. Therefore, equal sharing of electrons does not occur.

Polar covalent bonds

MY ANSWER

Nitrogen is more electronegative than hydrogen, leading to an unequal sharing of electrons, which is the definition of polar covalent bonds.

Ionic bonds

Ionic bonds require transfer of electrons from a cation to an anion, which does not occur in this molecule.

Hydrogen bonds

Hydrogen bonds are due to attraction between polar molecules, and they are not found within molecules.
