CHAPTER

29Organic chemicals

In plain English

This section covers organic chemicals known as acyclic hydrocarbons. It separates these goods based on whether they are saturated or unsaturated. Unsaturated varieties are further divided by specific types such as ethylene, propene, butene, and butadiene. Any other unsaturated acyclic hydrocarbons not listed elsewhere fall into the final category.
