Chapter 26, Problem 26.35P

Interpretation Introduction

(a)

Interpretation:

The structure of $\text{N-vinylpyrrolidone}$ is to be drawn.

Concept introduction:

Trivial names of compounds consist of two parts prefix and suffix. The suffix corresponds to the root name of the compound and the prefix corresponds to substituents on the root.

Interpretation Introduction

(b)

Interpretation:

$\text{Poly(N-vinylpyrrolidone)}$ can be synthesized by heating the monomer $\text{N-vinylpyrrolidone}$ in the presence of a small amount of ${\text{H}}_{\text{2}}{\text{O}}_{\text{2}}$. The initiation step and the first two propagation steps of this polymerization mechanism are to be drawn.

Concept introduction:

Hydrogen peroxide, ${\text{H}}_{\text{2}}{\text{O}}_{\text{2}}$ is a radical initiator which undergoes homolysis of the $\text{O-O}$ bond to form two hydroxyl radicals under heating or irradiation condition. In most of the free radical reactions, it is used as a source of a radical initiator. A very small quantity of initiator is sufficient for the reaction.
