[edit] 11.1 Homologous series

• A homologous series is a set of compounds with one repeating functional group

[edit] Physical Properties of Alkanes

• As chain length increases, so does boiling point, as an increased number of electrons causes stronger Van de Waal forces
• The increase in boiling temperature is rapid at first, but flattens off

And I was just wodnrenig about that too!

[edit] 11.3 Other Functional Groups

Functional Group Name	Functional Group
Aldehyde	-CHO
Ketone	-CO-
Alcohol	-OH
Carboxylic Acid	-COOH
Amine	-NH2
Amide	-CONH2
Halogenoalkane	-X (Any Halogen)
Ester	-COO-
Ether	-O-
