(a) Interpretation: The curved arrows that show the movement of electrons in step [1] are to be added. Concept introduction: In the representation of a chemical reaction , the movement of electrons is shown by the curved arrows. This method shows the movement of electrons of electrons in resonance structures as well.

Question

The curved arrow notation introduced in Section 1.6B is a powerfulmethod used by organic chemists to show the movement of electronsnot 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 andformed in a reaction. Consider the following three-step process. (a) Addcurved arrows in Step [1] to show the movement of electrons. (b) Use thecurved arrows drawn in Step [2] to identify the structure of X. X isconverted in Step [3] to phenol and HCl.
