Aims:1. Discuss the cycloalkane family.
Homologous series
Look similar
Same first name
All ring structures
CycloalkanesCycloalkanes• The cycloalkanes are another series of
hydrocarbons. • The carbon atoms form a ring and all
carbon to carbon bonds are saturated (carbon to carbon single bonds).

Cycloalkanes – Homologous Cycloalkanes – Homologous seriesseries1.All cycloalkanes can be represented by
a general formula which is:
2.They all have similar chemical properties
3.There is a link between their physical properties and their melting and boiling points.

Isomers- Have the same molecular formula but
different structural formula.

Butene and cyclobutane are isomers because they both have the molecular formula C4H8 but their structures are different.
There are two isomers of butane, both with the molecular formula C4H10.
Butane 2-methylpropane
The larger the hydrocarbon, the more isomers are possible. Can you try to draw 3 isomers for pentane?
