Concept explainers
(a)
To determine: The important resonance forms of the given free radical.
Interpretation: The important resonance forms of the given free radical are to be drawn.
Concept introduction: The delocalization of lone pair or free electrons from one place to another is known as resonance. The stability of compound depends upon the number of resonating structures. More the resonating structures of compound more will be its stability.
