a.
To determine:
The dipole moment arrow for each polar covalent bond of the given lewis structure.
Introduction:
The polarity of a bond is directly related to the electronegativity difference. A polar bond corresponds to a non-uniform distribution of the electron cloud between two nonmetals. Thus, the bond formed between them is a covalent bond. This corresponds to the fact that an atom with higher electronegativity value will show a higher affinity for electrons.
A non-polar bond is formed by a mononuclear diatomic molecule that corresponds to a uniform distribution of the electron cloud. These molecules do not possess diploe moment.
b.

If the molecule is polar or nonpolar and to draw the molecular dipole.
