Similarly, a functional group can be referred to as primary, secondary, or tertiary, depending on if it is attached to one, two, or three carbon atoms.Ĭlassification of alcohols: Alcohols are a common functional group (-OH). The first carbon atom that attaches to the functional group is referred to as the alpha carbon the second, the beta carbon the third, the gamma carbon, etc. The atoms of a functional group are linked together and to the rest of the compound by covalent bonds. Functional groups also play an important part in organic compound nomenclature combining the names of the functional groups with the names of the parent alkanes provides a way to distinguish compounds.
The same functional group will behave in a similar fashion, by undergoing similar reactions, regardless of the compound of which it is a part. In organic chemistry, a functional group is a specific group of atoms or bonds within a compound that is responsible for the characteristic chemical reactions of that compound.

You can download the updated version using the button below. Additionally, I’ve made it so that the colour circles around each functional group actually have some significance, rather than just being arbitrary.
ALCOHOL FUNCTIONAL GROUP UPDATE
UPDATE JULY 2014 I’ve updated the design of this graphic to include a few more functional groups and also make the design clearer. I’ve also produced three teaching versions of an earlier version of this graphic ( 1, 2 & 3) with varying amounts of information blanked out to allow pupils to fill them in.Įdit: updated to add in explanation of what R and X stand for in the various formulae. More complicated chemical molecules may contain more than one functional group within their structure, which can sometimes affect the chemical reactions they undergo. The names of organic molecules are systematic references to the functional groups within the molecule, and can thus be used to identify these. It’s nothing ground-breaking, but hopefully other teachers will find it useful.Ī functional group in chemistry is the part of the molecule that gives it its particular reactivity simple molecules that contain the same functional group in their structure can be expected to react in similar ways. The idea for this was to present the various organic compounds that pupils need to learn at A level in a straightforward manner, simply with the formulae, name, and a naming example of each. Today’s graphic is a little more basic, but is something that I’m hoping to eventually develop into an organic reaction map.
