Chapter 6, Problem 77QRT

(a)

Interpretation Introduction

Interpretation:

The Lewis structure of ${\text{C}}_{\text{8}}{\text{H}}_{\text{10}}$ molecule has to be written along with whether the molecule represents alkane and aromatic has to be classified.

Concept Introduction:

A Lewis structure is also known as Lewis dot diagrams or electron dot structures.  The bond between atoms and lone pairs of electrons that is present in the molecule.  Lewis structure represents each atom and their position in structure using the chemical symbol.  Excess electrons forms the lone pair are given by pair of dots, and are located next to the atom.

The basic formula for alkane, alkene, or alkyne can be written as,

    $\overline{\begin{array}{l}\text{n}\text{2n+2}\text{2n}\text{2n-2}\\ \underset{\_}{\text{(alkane)}\text{(alkene)}\text{(alkyne)}}\\ {\text{C}}_{\text{6}}{\text{H}}_{\text{x}}\text{6}\text{x=14}\text{x=12}\text{x=10}\\ {\text{C}}_{\text{8}}{\text{H}}_{\text{x}}\text{8}\text{x=18}\text{x=16}\text{x=14}\\ \underset{\_}{{\text{C}}_{\text{10}}{\text{H}}_{\text{x}}\text{10}\text{x=22}\text{x=20}\text{x=18}}\end{array}}$
