Organic chemistry is the chemistry of carbon containing compounds.

A hydrocarbon is a substance that contains only carbon and hydrogen.

There are three main hydrocarbons on the course – alkanes, alkenes and alkynes.

A homologous series is a series of compounds:

• of similar chemical type.
• that show gradual change in their physical properties.
• all are prepared in a similar way.
• have a common general formula

• differ one from the next by a

• group.

The Alkanes

The first homologous series we deal with is calles the alkanes (The ending tells us the chemical family).
