Interpretation Introduction

Interpretation:

The resonance structure for the given radical should be identified.

Concept introduction:

Radical or free radical: The unpaired valence electron of an atom, molecule, or ion is called as radical. The stability order for radical is as follows,

$\text{benzylic}\text{>}\text{allylic}\text{>}\text{tertiary}\text{>}\text{secondary}\text{>}\text{primary}\text{>}\text{methyl}$

Resonance: The molecule is said to have resonance structures if it has more than one structure by migrating lone pair, radical or the phi bonds present in the molecule.

Resonance stabilization: Due to the delocalization of electrons within the molecule the overall energy becomes lower and makes the molecule more stable.
