Chapter 11, Problem 11.55E

Interpretation Introduction

(a)

Interpretation:

The structural formula of the given compound is to be predicted.

Concept introduction:

Those compounds which have the same molecular formula but have different arrangements of atoms are known as isomers. The phenomenon is called as isomerism. The isomers are generally classified as structural isomers and stereoisomers. Stereoisomers are further divided into two categories diastereomers and enantiomers.

Answer to Problem 11.55E

The structural formula of the given compound is shown below as,

Explanation of Solution

The given compound is ${\text{C}}_{\text{6}}{\text{H}}_{\text{14}}$ that is a normal alkane. The structure of ${\text{C}}_{\text{6}}{\text{H}}_{\text{14}}$ is represented with six carbon atom chain. The terminal carbon atoms will have three hydrogen atoms attached to them and other carbon will have two hydrogen atoms attached to them. Therefore, the structural formula of the given compound is shown below as,
