In terms of polarity, what best describes the molecule NH3?
A) A non-polar molecule composed of polar covalent bonds
B) A polar molecule composed of nonpolar covalent bonds
C) A polar molecule composed of polar covalent bonds
D) A non-polar molecule composed of nonpolar covalent bonds
Molecular Polarity
This concept describes the distribution of electrical charge over the atoms joined by chemical bonds in a molecule, determining the molecule’s overall polarity.
Polar Molecule
A molecule with an uneven distribution of charge due to differences in electronegativity between bonded atoms, resulting in a dipole moment.

Final Answer :
C
Explanation :
Polarity in molecules arises from the distribution of electrical charges due to the electronegativity differences between atoms. A molecule can be overall polar if it contains polar covalent bonds and if the molecular geometry does not cancel out the dipole moments. Thus, a molecule described as NH3, without specific structural details, would likely have polar covalent bonds due to the differences in electronegativity between nitrogen (N), hydrogen (H), and sulfur (S), leading to an uneven charge distribution.
