Concept explainers
Interpretation:
The explanation that accounts for the fact that the radical
Concept introduction:
The order of relative stability of the radicals formed during a reaction are as follow:
The stability of the radical decides the path of the reaction. The path of the reaction will help is determining the products formed and can also be used in identifying the major product or thepreferred mechanism for a given reaction.
Hyperconjugation is an interaction between the sigma bond electrons and the adjacent atom’s empty or partially filled p-orbitals in improving the stability of the whole molecule.

Compare the relative stabilities of the intermediates in this mechanism with those you drew for chain branching in the cationic polymerization of styrene. Explain why chain branching is less common in this anionic polymerization.arrow_forward
