The resonance structures of the benzene molecule are to be drawn and the fact that benzene is more stable than the ring containing the three carbon-carbon double bonds is to be explained. Concept Introduction: An ionic compound is a compound in which positive ions and negative ions are held together by electrostatic forces. In a Lewis structure, a graphic diagram represents the bonding between atoms of a molecule and the lone pairs of electrons. The capability of an atom to captivate a bonding pair of electrons leads to an electronegative atom. In a resonance structure, electrons have the capability to move in order to stabilize the molecule, and all the structures should have the same number of electrons and the same number of lone pairs.

Concept Introduction:
An ionic compound is a compound in which positive ions and negative ions are held together by electrostatic forces.
In a Lewis structure, a graphic diagram represents the bonding between atoms of a molecule and the lone pairs of electrons.
The capability of an atom to captivate a bonding pair of electrons leads to an electronegative atom.
In a resonance structure, electrons have the capability to move in order to stabilize the molecule, and all the structures should have the same number of electrons and the same number of lone pairs.
