(a) Interpretation: Whether the given structure is a legitimate Lewis structure is to be determined. Concept introduction: For a valid Lewis structure of a molecule, the atoms must not exceed their normal valency. In general, this means atoms from the 2 nd row onward, of the periodic table, must follow the octet rule. The exceptions to this rule are elements from the third row like S, P, etc., which are capable of expanding their octets to a maximum of twelve valence electrons. A hydrogen atom cannot have more than two valence electrons.
