Introduction

• Alkenes are a homologous series and are a type of hydrocarbon.
• Alkenes are unsaturated hydrocarbons as they contain a carbon double bond.
• Alkenes are immiscible with water and other polar solvents as they are non-polar and cannot hydrogen bond to water molecules.
• Alkenes are miscible with non-polar solvents.
• Alkenes are non-polar because carbon and hydrogen have similar electronegativity values and dipoles are not created.
• The general formula of alkenes is Cn H2n.
• The functional group of alkenes is the carbon double bond.
• Structural isomerism occurs in alkenes when 4 carbon atoms are reached.
• In alkenes, the longest chain must contain the carbon double bond.
