Introduction
Muhtasari
Carbon is unique among elements: it can form four strong covalent bonds with other atoms, including itself, creating chains, rings, and branches of almost infinite variety. This ability gives rise to millions of carbon compounds, from plastics and fuels to medicines and DNA.
In this lesson you will learn what organic chemistry is, what a homologous series means, and how organic molecules are named and represented.
Malengo
- Know that a hydrocarbon is a compound of hydrogen and carbon only
- Understand how to represent organic molecules using molecular formulae, general formulae, structural formulae and displayed formulae
