The resonance structures for the given Lewis formulas are to be written by curved arrows and the stabilities of two Lewis formulas are to be compared and the more stable structure, if any, is to be identified. Concept introduction: Maximizing the number of bonds and obey the octet rule are the main factors that contribute to the stability of a resonance structure. When two or more Lewis structure satisfy the octet rule, the structure which have the smallest charge separation is the major contributor. Among all Lewis structural formulas that satisfy the octet rule, and in which one or more atoms bears the formal charge. The major contributor structure is one in which have the negative charge on the most electronegative atom.
