Draw Lewis structures for the following molecule and ions. For each of these structures
a) Draw Lewis structures for the following molecule and ions. For each of these structures, the octet rule must be satisfied, and all lone pairs must be shown. Name the molecular geometry for each and also specify if they are polar. If a molecule has more than one resonance structure, draw just the best one. Show formal charges only if they are not zero. b) Which compound(s) above will not have ideal bond angles about the central atom? Circle your choice(s). CNF ...
