Concept explainers
(a)
Interpretation:
The polarity of the given molecule is to be determined.
Concept introduction:
The polarity of the molecule depends on dipole moment. A dipole moment is a vector, which has both magnitude and direction, so the net dipole moment of a molecule is shown by adding the vectors of the bond dipoles together. Polarity of a molecule as a whole also depends on symmetry. Tetrahedral molecules that have polar covalent bonds can be polar or non-polar, depending on their symmetry.
