Which of the following molecules is/are nonpolar? i.CH₄ ii.CH₃Cl iii.CH₂Cl₂ iv.CHCl₃ v.CCl₄ A)i only B)iii only C)i and v D)ii and iv E)i, iii, and v

Question

Quizplus · Accepted Answer

Molecules i and v have no polar bonds and are symmetric, which makes them nonpolar. The other molecules have polar bonds, making them polar unless the molecular geometry cancels out the polarity (as in the case of molecule iii, which has two polar bonds of equal strength and opposite direction, cancelling out the polarity of the molecule). Molecules ii and iv have polar bonds and are not symmetric, so they are polar.
