Chapter 2.10, Problem 26CC

(a)

Interpretation Introduction

Interpretation:

The significant resonant structures have to be drawn.

Concept Introduction:

Resonance is a method to relating to describe about delocalized electrons inside certain molecules or polyatomic ions where the Lewis structure can’t be expressed. A molecule or ion containing delocalized electrons can be represented by using several similar structures such structures are called as resonance structures or canonical structures.

The delocalization of electron lowers the potential energy of the substance and making it more stable than any of the contributing structures. The variation in the potential energy of the actual structure and that of resemblance structure with lowest potential energy is known as resonance energy or delocalization energy.

Curved arrows:

The necessary tools to draw perfect resonance structure are curved arrows. Curved arrows don’t represent the flow of electrons.  A tail and a head can be seen in curved arrow.

A head and tail of every arrow are to be drawn in the exact location. The tail represents where the electrons are originated, and the head represents the place where the electrons are going.
