What are numbers in scientific names used to represent?

What carbon the functional group(s) are placed onto. The # always goes before the functional group.

What do di-, tri-, and tetra- mean?

They tell you if there are multiple of the same functional group in a molecule.

What do ortho-, meta-, and para- mean in naming?

They stand for the carbons the functional groups are placed on in a benzene ring. 1,2: 1,3: and 1,4.

Trivial Names

Commonly used names in Ochem that are not based on the molecules structure.

Acetone

Acetaldehyde

Acetone with a hydrogen instead of a carbon

Acetic Acid

Acetone with an OH instead of carbon

Formic Acid

Acetic acid but with a hydrogen instead of carbon

Ethyl Acetate

As the game suggests an ethyl attached to an acetone

Ether

A solo oxygen attached to two carbons

Benzene

Sole six sided ring

Toluene

Benzene ring with one carbon attached

Phenol

A phenyl with an alcohol attached
