Organic Chemistry

Use this mind map to learn the differences between the Alkanes and Alkenes.

Alkane

An alkane consists of hydrogen and carbon atoms arranged in a tree structure in which all the carbon–carbon bonds are single.

Reaction of Alkanes

Identify the general reactions of alkanes.

Keypoints:

• Alkanes are stable compounds and are generally unreactive.
• The most important application of alkanes is in oxidation reactions; they are used in internal combustion engines as fuel.

Properties of Alkanes

Name the properties of Alkanes.

Alkene

An alkene is an unsaturated hydrocarbon that contains at least one carbon–carbon double bond.

Reaction of Alkenes

Alkenes undergo addition reactions, in which two molecules combine to form a larger one. Addition takes place across the double bond (C=C) where the weaker pi bond is broken in favour of the formation of stronger sigma bonds.

Name the common addition reactions of Alkene.
