Question
Chapter 1, Problem 1.54P
Interpretation Introduction
Interpretation: Four additional resonance structures for the given cation and its resonance hybrid are to be drawn.
Concept introduction: Resonance structures are possible for those compounds which cannot be represented by a single Lewis structure. The arrangement of atoms in resonance structures remains same but the position of non-bonded electrons and pi bonds is different.
