General things to remember
Always write down the formula.
In chemistry all the measurements should be in grams, unless otherwise stated.
Make sure that you are using the proper measurement for the formula.
Remember to square numbers where there is a square in the formula.

• If there are any identical side chains use the prefixes di, tri and tetra.
• Always name in alphabetical order excluding di, tri and tetra.
• Numbers should be separated from letters by a dash (-).
• Numbers are separated by commas (,).
• Do not indicate where the functional group is for esters or carboxcylic acids, as the
functional group will always be on the first carbon numbering is redundant.
• Dienes (two double bonds in alkenes) get an “a” before the suffix dienes for
euphonic purposes. Eg) buta-1,3-diene is correct, but buta-1,3-diene is not.
• Diols get an “e” before the diol suffix for euphonic purposes. Eg) butane-1,3-diol is
correct, but butan-1,3-diol is not.

Naming Alkanes
• Single bonds between carbons.
• Find the longest carbon chain.
• Start numbering from the closest sidechain.
• Name in alphabetical order excluding di, tri, tetra …

Naming Alkenes
• One or more double bonds between carbons.
• Find the longest carbon chain.
• The double bond takes preference over the sidechains.
