 Alkenes and Alkynes Comments
Consider the unsaturated compound, ethene (C2H4): The Pi electrons in the double bond are vulnerable to attack by electron-seeking species.
Mabel (Dr. Mabel Rodrigues) ========================================================= John : An alkene refers to a hydrocarbon compound having a carbon-carbon double bond, while an alkyne is a hydrocarbon compound having a carbon-carbon triple bond.
These bonds are called unsaturated because you can break the double or triple bond by adding a functional group to one or both of the carbon atoms, by an addition reaction, thereby making all of the bonds to the carbon atoms single bonds.
