🤓 Based on our data, we think this question is relevant for Professor Harris' class at UF.

Solution: Which of the following statements concerning polar molecules is false? a. There must be at least one polar bond or one unshared pair of electrons on the central atom. b. If there are more than one polar bond, they must not be symmetrically arranged so that their polarities cancel. c. If there are more than one unshared pair of electrons on the central atom, they must not be symmetrically arranged so that their polarities cancel. d. There must be an odd number of polar bonds so that their polarities not cancel. e. A molecule with symmetrically arranged polar bonds can be polar if the central atom is bonded to atoms of different elements.
