Alkanes are saturated hydrocarbons with single bonds that have a tetrahedral shape, giving them bond angles of 109.5 degrees. They freely rotate due to their open mobility from having fewer electrons. Examples of alkanes include butane, hexane, and 3-ethyl pentane. Alkanes are commonly used as fuels like kerosene and gasoline as well as anti-corrosives.

1. Alkanes
By:Evan Johnson

2. Definition:
● Alkanes have a saturated single bond
● Their bond angle is 109.5 degrees because of its tetrahedral
shape
● The rotation of these alkanes is free with its open mobility and
lesser bond

3. Butane contains 4 Carbons & 10
Hydrogen molecules
2,3 dimethyl
Hexane’s parent
chain has 6 total
carbons and 2 methyl
groups (which is off
the 2nd and 3rd
carbon)

4. 3 ethyl pentane’s main/parent chain contains 5 carbons and contains an ethyl group off
of the 3rd carbon
Picture Slide II

5. Examples
•Some examples of alkanes being used are from polar
regions that helped develop fuels. Such is kerosene
and gasoline.
•They also help with anti-corrosive

6. Summary
● Alkanes have a saturated hydrocarbon single bond
● Their bond angle is 109.5 degrees because of its tetrahedral
shape
● The rotation of these alkanes is free with its open mobility and
lesser bond because of their lack of electrons
