Chapter 22, Problem 11STP

Interpretation Introduction

Interpretation: To give the name of a hydrocarbon having the molecular formula ${\text{C}}_6{\text{H}}_6$ .

Concept Introduction: Hydrocarbons are composed of carbon and hydrogen atoms. The categories of hydrocarbons are as follows:

• Alkane
• Alkene
• Alkyne
• Arene

Answer to Problem 11STP

The hydrocarbon with a molecular formula ${\text{C}}_6{\text{H}}_6$ comes under arene.

Explanation of Solution

Arenes are hydrocarbons that consist of alternating double and single bonds between carbon atoms forming rings. The hydrocarbon with a molecular formula ${\text{C}}_6{\text{H}}_6$ is benzene which consists of six carbon atoms having alternating double and single bonds.

Conclusion

Thus, ${\text{C}}_6{\text{H}}_6$ is an arene i.e.,benzene.
