Chapter 23, Problem 94A

Interpretation Introduction

Interpretation: Most likely to be a good source of aromatic compounds- Petroleum or Coal needs to be answered.

Concept Introduction: Compounds that have conjugated planar rings with delocalized pi-electrons. They are also known as aromatics and arenes.

Answer to Problem 94A

Petroleum is more likely to be a good source of aromatic compounds.

Explanation of Solution

Given Information: Petroleum or Coal- Most likely to be a good source of aromatic compounds.

There are two primary sources of simple aromatic hydrocarbons: coal and petroleum. Most of the many chemicals that make up coal's complex mixture are long-chain molecules.

During the pyrolysis of coal, a significant portion is transformed into char and several e aromatic compounds are synthesized.

The method of catalytic re-forming, also known as hydroforming, is used to manufacture aromatic hydrocarbons from petroleum.

Conclusion

Petroleum is more likely to be a good source of aromatic compounds.
