The enamine prepared from acetone and dimethylamine is shown here in its lowest-energy form.
(a) What is the geometry and hybridization of the nitrogen atom?
(b) What orbital on nitrogen holds the lone pair of electrons?
(c) What is the geometric relationship between the p orbitals of the double bond and the
nitrogen orbital that holds the lone pair? Why do you think this geometry represents
the minimum energy?
In an attempt to synthesize compound C through a two-step process, a chemist discovered after
completing the first step that they had inadvertently produced two distinct compounds, A and B.
Upon examining the infrared spectroscopy (IR) results, it was observed that both A and B exhibited
peaks indicative of a ketone and an ester group. Please provide the molecular structures of A and B.

In a chemical experiment, they noticed that both components, A and B, from a combined
sample turned into a new compound, C, during the following stage. The task is to
determine what compound C looks like and explain how compound A or B changes into
compound C through a reaction. Compound C should be the primary molecule
containing carbon created in this process, not just a by-product.

This is accomplished when a free radical (or UV light) encounters a phenol group, turning the phenol group into a radical. However, contrary to typical radical behavior, the structure of the phenol radical can neutralize (or quench) the unpaired electron. Specifically, the phenol structure neutralizes (or quenches) the unpaired radical electron by doing the following: taking the electron and ---------.
