Chapter 9, Problem 9.33QP

Interpretation Introduction

Interpretation: The Lewis structures including resonance forms of $\text{C}{\left(\text{CN}\right)}_3^{-}$ and the structure which contributes most to the bonding is to be determined.

Concept introduction: The structures which have fully filled octet of all the atoms present in the molecule contribute most to the bonding.

To determine: The Lewis structures including resonance forms of $\text{C}{\left(\text{CN}\right)}_3^{-}$ and the structure which contributes most to the bonding.
