Part B. Which statement best describes the polarity of CH3Cl?
(a) The molecule is always polar.
(b) The molecule is always nonpolar.
(c) Depending on the arrangement of outer atoms, this molecule could be polar or nonpolar.
A molecule can be polar or nonpolar depending upon the nature of the bonds and the shape of the molecule. For a molecule that has different outer atoms the molecular symmetry will decide the polarity.
If the molecular geometry is such that the dipole moments of each polar bond cancel each other then the molecule is nonpolar.
However, if the the molecular geometry is such that the dipole moments of each polar bond don’t cancel each other then the molecule is polar.
