Chapter 13.21, Problem 30P

Interpretation Introduction

Interpretation:

The chemical equations that not only relate the mechanism but also outline the structure of the intermediate that forms in the rate determining step of the addition-elimination reaction of hexafluoro benzene and sodium methoxide are to be determined.

Concept introduction:

Nucleophilic aromatic substitution reactions involve the substitution of a leaving group by an upcoming nucleophile.

The aromatic ring is itself act as a nucleophile, hence the ring undergoes this substitution only in the presence of a strong electron withdrawing so that it stabilized the negative charge on the ring.
