Alkenes

• They are unsaturated hydrocarbons (carbon carbon double bond)
• General formula of CnH2n
• Are reactive due to the double bond which has a high electron density
• No rotation around the double bond or the carbons attached to the carbon double bond
• Can form 2 types of isomers: position and geometrical
• Position isomers is the movement of the double bond to a different carbon
• Geometrical isomerism is a form of stereoisomerism, E-Z isomerism
