Provide the major resonance structures of the ion which results when the most acidic hydrogen of cyclopentadiene is lost.

Resonance Structures

Different Lewis structures that represent the same molecule, used to depict delocalized electrons within certain compounds.

Cyclopentadiene

A cyclic hydrocarbon with the formula C5H6, known for its role in Diels-Alder reactions.

Acidic Hydrogen

A hydrogen atom bonded to an electronegative atom, making it easily released as a proton (H+).
