Naming cycloalkanes with side groups

Naming Cycloalkanes with Side Groups

Number of Naming

side groups

OneSide group name goes in front of the cycloalkane name.

TwoNumber the ring in the direction that gives the lowest numbers to the side groups.

Aromatic compounds and benzene

Aromatic Compounds and Benzene

Aromatic compounds contain benzene.

Benzene, C6H6 , is represented as a six carbon ring with 3 double bonds.

Two possible can be drawn to show benzene in this form.

Benzene structure

Benzene Structure

The structures for benzene can also be written as a single structure where the alternating double bonds are written as a circle within the ring.

Aromatic compounds in nature and health

Aromatic Compounds in Nature and Health

Many aromatic compounds are common in nature and in medicine.

Naming aromatic compounds

Naming Aromatic Compounds

Aromatic compounds are named with benzene as the parent chain. One side group is named in front of the name benzene.

Naming aromatic compounds1

Naming Aromatic Compounds

When two groups are attached to benzene, the ring is numbered to give the lower numbers to the side groups. The prefixes ortho (1,2), meta (1,3-) and para (1,4-) arealso used.

Timberlake LecturePLUS 1999


Some common names

Some Common Names

Some substituted benzene rings also use a common name. Then naming with additional more side groups uses the ortho-, meta-, para- system.
