Chapter 16.SE, Problem 45MP
Interpretation Introduction

a)

Study Guide with Student Solutions Manual for McMurry's Organic Chemistry, 9th, Chapter 16.SE, Problem 45MP , additional homework tip  1

Interpretation:

A structure for methyl orange, an azo dye, produced when the two reactants shown react is to be drawn and the electron pushing mechanism for its formation is to be shown.

Concept introduction:

The diazonium cation can act as an electrophile and can attack aromatic rings. The dimethylamino group is an o- and p- directing group. Hence the diazonium cation can attack the ring at the p-position to yield a carbocation intermediate. The intermediate then can lose a proton to yield the desired product. This reaction is known as coupling reaction.

To draw:

The structure of methyl orange, an azo dye, produced when the two reactants shown react and to show the electron pushing mechanism for its formation.

This organic molecule is dissolved in an acidic aqueous solution: OH OH A short time later sensitive infrared spectroscopy reveals the presence of a new C = O stretch absorption. That is, there must now be a new molecule present with at least one C = O bond. In the drawing area below, show the detailed mechanism that could convert the molecule above into the new molecule.
