Organic Chemistry: Naming + Alkanes, Alkenes, and Alkynes

All things organic need a name.

• The differences with each group is how the name ends, in this case Alkanes end with an 'ane'.

Methane!

• Depending on how many hydro Carbons there are the beginning of any name would start with:       -Methane, Ethane, Propane, Butane, Pentane, Hexane, Heptane, Octane, Nonane, and Decane. (these are also all Alkenes!)

A helpful little chart for naming groups of atoms.

Alkenes

• Just like Alkanes, Alkenes end with an 'ene'
• The difference with Alkanes is that it has a double bond somewhere in the chain.
• When counting Alkenes always make note that the double bond should be the lowest number infront of the parent chain.
• An example of an Alkene would be CH2=CH2, ethene

Examples of Alkenes.

Alkynes

• Just like the other two, Alkynes end with an 'yne'
• This time alkynes have a triple bond somewhere in the chain.
• Just like Alkanes, Alkynes should have the triple bond be the lowest number infront of the parent chain.
• An example of an Alkyne would be CH=CH, ethyne

Examples of Alkynes.
