Learning Objectives

  • Chemicals can be classified based on their structure and applications.

  • Aliphatic and aromatic compounds represent fundamental classifications within organic chemistry.

  • Chemical monitoring is essential for prioritizing pollutants to track their presence and assess their risks.

Key Concepts

Aliphatic Compounds

Organic compounds consisting of carbon and hydrogen, characterized by straight or branched chains or non-aromatic rings.

Aromatic Compounds

Compounds containing one or more benzene rings, often with distinct stability and reactivity due to resonance.

Polyaromatic Hydrocarbons

Complex organic compounds that consist of multiple fused aromatic rings, which can pose environmental and health risks.

Chemical of Concern

Any chemical that poses potential human health risks and needs to be monitored due to its toxicity or environmental impact.

Volatile Organic Compounds (VOCs)

Organic chemicals that have a high vapor pressure at room temperature, making them significant pollutants in industrial processes.
