Study Notes
Alkanes: The Basics
- Alkanes are hydrocarbons, which means they are made up of only carbon and hydrogen atoms.
- They have single bonds between carbon atoms and are considered saturated hydrocarbons because they contain the maximum number of hydrogen atoms for each carbon atom.
Why Paraffins?
- Alkanes are also known as paraffins because they are relatively unreactive.
- The word "paraffin" comes from the Latin word "parum affinis," meaning "little affinity."
Geometry of Carbon in Alkanes
- Carbon in alkanes has a tetrahedral geometry. This means the four bonds around each carbon atom are arranged in a three-dimensional shape like a pyramid with a triangular base.
Bond Type in Alkanes
- Alkanes solely contain single bonds, specifically carbon-carbon (C-C) and carbon-hydrogen (C-H) single bonds.
Classification of Hydrocarbons
- Hydrocarbons are classified based on the type of bonds between carbon atoms.
- Alkanes are considered saturated hydrocarbons, meaning they only have single bonds between carbon atoms.
- Other types include unsaturated hydrocarbons, which include alkenes (double bonds) and alkynes (triple bonds).
