Concept introduction:
For a species, each valid Lewis structure is called a ‘resonance structure’ or a ‘resonance contributor’. A resonance hybrid is a weighted average of all resonance contributors. A partial bond is represented in a resonance hybrid by a dashed line connecting the two atoms. In the resonance hybrid, partial bonds are shown which represent the atoms over which the electrons are being delocalized.

A
1.88/The curved arrow notation introduced in Section 1.6B is a powerful method used by organic chemists to show the movement
of electrons not only in resonance structures, but also in chemical reactions. Because each curved arrow shows the movement
of two electrons, following the curved arrows illustrates what bonds are broken and formed in a reaction. Consider the following
three-step process. (a) Add curved arrows in Step [1] to show the movement of electrons. (b) Use the curved arrows drawn in
Step [2] to identify the structure of X. X is converted in Step [3] to phenol and HCI.
