Chapter 23, Problem 12STP

Interpretation Introduction

Interpretation:

The condensed structural formula of heptane needs to be determined.

Concept introduction:

Structural formula of a molecule is determined by considering the longest carbon chain first and then by naming the substituents attached to this chain.

Answer to Problem 12STP

The condensed structural formula of heptane is ${\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{3}}$

Explanation of Solution

To determine the structural formula, we have to first see the name of the compound given which is heptane. By the name heptane we know that it will have seven carbon atoms and it is an alkane so it will have only single bonds.

So, the condensed structural formula of heptane is ${\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{3}}$.

Conclusion

${\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{3}}$ is the condensed structural formula of heptane.
