Interpretation Introduction

Interpretation:

The reason for the stabilization of radical formed in the reaction of the red $C-H$ bond with oxygen has to be identified.

Concept introduction:

Autoxidation involves reaction of a $C-H$ bond, (usually allylic one) with oxygen under radical initiation condition. The product is a hydroperoxide.

Mechanism involves a radical chain process in which resonance-delocalized allylic radical intermediates reacts with molecular oxygen to give peroxy radical that continues the radical chain.

Major product is more substituted double bond.
