Question

              

                A. A trigonal planar molecular shape has four atoms attached to the central atom.                 B. When counting the number of electron groups on the central atom, a double bond counts as two groups.                 C. The unshared pairs of electrons are unimportant in both the Lewis structure and in VSEPR theory.                 D. The trigonal pyramidal shape has three atoms and one unshared pair of electrons on the central atom.                 E. It is not necessary to calculate the number of valence electrons available in a given molecule before using VSEPR to predict the shape of that molecule.
