Lesson 5: Naming of alkenes

Wednesday, August 18, 2010

How do we give alkenes their names?

- Find the longest continuous carbon chain in the compound containing the C=C bond (parent chain)

- Specify the position of the double bond by numbering the position of the double bond, starting from the end nearest the bond.

- Name the group joined to the chain and state the number of carbon atom in which it is joined to.

- If the chain has 2 or more similar groups joined to it, prefixes like di-, tri-, tetra- is used to indicate the number of groups present.

- If the chain has 2 or more different groups joined to it, the groups are written in an alphabetical order/increasing size.
