(a)
Interpretation: The polar bonds in the given molecule are to be labeled. The direction of net dipole is to be indicated, if possible.
Concept introduction: Electronegativity difference between the atoms of a molecule is used to identify the polar bonds. The direction of the bond dipoles is predicted with the help of electronegativity difference between the atoms. Polar molecules have net dipole moment while non polar molecules have no net dipole.
