- a model of each molecule shown above: Is the molecule in the left box the same moleculeas the molecule in the right box? Use your models to answer the question, and recall that...Which statement A-D regarding formal charge is not correct? Select one: a. Formal charge on an atom in a bond is determined by the electronegativity of that atom. b. The formal charge of an atom in a molecule is the actual charge on that atom. c. The most stable (lowest energy) Lewis structure is the one with the most formal charges equal to zero or closest to zero. d. Any negative formal charges should be on the more or most electronegative element. e. Statements A-D are all correct. Clear my choiceCould we cut just one bond in the "starting" molecule shown in the drawing area below to create this "target" molecule? The target molecule. If so, highlight the bond to be cut. If not, check the box under the drawing area that says Not possible. Note: it's OK if cutting the bond creates more than one molecule, as long as one of them is the target molecule. Not possible. X H H-C-H H-O-H H 3 Note for advanced students: what we mean by "cutting" the bond here is breaking the bond and attaching H atoms to each dangling end, like this: H H-C-0-H H
