Alkenes & Alkynes

-Carbon can form double & triple bonds with carbon atoms
-When multiple bonds form fewer hydrogens are attached to the carbon atom
-Naming rules are almost the same as with Alkanes
                - The position of the double/triple bonds always has
                  the lowest number and is put in front of the parent chain

-Double bonds (Alkenes) end in -ene
-Triple bonds (Alkynes) end in -yne

 

 

TRANS & CIS BUTENE

 

-If two adjacent carbons are bonded by a double bond AND have side chains on them two possible compounds are possible

 

MULTIPLE DOUBLE BONDS

 

-More than one double bond can exist in a molecule
-Use the same multipliers inside the parent chain
