Question

Question: 21-62 What is the structure of the polymer produced by treatment of $\mathbf{\beta }\mathbf{-}\mathbf{propiolactone}$ with a small amount of hydroxide ion?

                                       

Step-by-Step Solution

Answer

The polymer formed by treating  $\mathbf{\beta }\mathbf{-}$propiolactone with a tiny quantity of OH has the following structure:

Step 1: Introduction to the Concept

The arrangement of chemical bonds between atoms in a molecule (in anion or radical with many atoms), particularly which atoms are chemically bound to which other atoms with what kind of chemical bond, as well as any geometric shape information needed to uniquely identify the type of molecule.

Step 2: Solution Explanation

The lactone requires is opened by a little quantity of OH, while another lactone requires are attacked to create the polymer. This

Polymerization is achieved through step-growth polymerization, in which each step increases the chain length separately, i.e. chain length increases in discrete increments. Every stage is a nucleophile acyl substitution once again.
