Chapter 21, Problem 7E

Interpretation Introduction

Interpretation:

The molecular formula of the alkanes having 11 and 21 carbon atoms is to be determined.

Concept introduction:

Alkanes are the saturated hydrocarbons where carbon is bonded to four other carbon atoms via single bond only. The general formula of alkanes is ${\text{C}}_n{\text{H}}_{2n+2}$, $n$ is the number of carbon. If all the carbon atoms in alkane are arranged in a linear or continuous chain, the resulting hydrocarbon is called normal alkane. For example, methane $\left({\text{CH}}_{\text{4}}\right)$ and ethane $\left({\text{C}}_{\text{2}}{\text{H}}_{\text{6}}\right)$.
