Moiety (chemistry)

From Wikipedia, the free encyclopedia

Benzyl acetate has an ester functional group (in red), an acetyl functional group(circled with dark green) and a benzyloxy moiety (circled with light orange). Other divisions can be made.

In organic chemistry, a moiety (/ˈmɔɪəti/) is a part of a molecule[1][2] which is typically given a name as it can be found within other kinds of molecules as well.

The term moiety should be reserved to describe the larger characteristic parts of molecules and not used to describe smaller functional groups,[3][4] which are made up of atoms that participate in similar chemical reactions in most molecules that contain them.[5] In some instances moieties may be composed of yet smaller moieties and functional groups.

Moieties that constitute branches extending from the backbone of a hydrocarbon molecule, which can often be broken off and substituted with others, are called substituents or side chains.
