Interpretation:
The resonance structures for cyclopentadienyl anion to show the delocalization of the negative charge over all five carbons are to be drawn.
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.
