Concept explainers
Interpretation:
More stable contributing structure for each of the given structures is to be written, curved arrows are to be used which shows the transformation of the original Lewis formula to the new one and formal charges are to be specified.
Concept introduction:
The resonance structure with the greater number of covalent bonds contributes more to the resonance hybrid provided the octet rule is not exceeded for second-row elements.
A Lewis structure can have more than one structure; they are called resonating structures.
The movement of a pair of electrons is shown by curved arrows.
the structure in which the negative charge is present on the most electronegative atom and the positive charge is present on the least electronegative element is known as the major resonance contributor.
The species having the smallest separation of oppositely charged atoms is the major contributor.
