Question
Chapter 28.8, Problem 7P
Interpretation Introduction
Interpretation:
An explanation is to be suggested for the observation that branches shorter or longer than four carbonsare found infrequently in polyethylene.
Concept introduction:
During the intramolecular hydrogen transfer, the carbon atom at the end of the
fifth carbon.
This results in a transition state which is a cyclic arrangement of six atoms.
This reduces the randomness of the transition state as compared to the open chain polymer.
During this process, a primary free radical is converted to a more stable secondary free radical.
This step is exothermic since products of this step are more stable than the reactants.
