• Alkanes are saturated -they consist of single bonds between their carbon atoms.

• Alkenes are unsaturated - they consist of two bonds between their carbon atoms.

• Alkynes are unsaturated - they consist of a triple bond between their carbon atoms.

Alkanes are saturated -they consist of single bonds between their carbon atoms.

• General formula: CnH{2n+2}

• They are hydrocarbons i.e. they consist of hydrogen and carbon atoms

Alkenes are unsaturated - they consist of two bonds between their carbon atoms.
-General formula: CnH{2n}

Alkynes are unsaturated - they consist of a triple bond between their carbon atoms.
-General formula: CnH{2n-2}
