Thus, (CH 3 CO) 2 O is called acetic anhydride. Mixed (or unsymmetrical) acid anhydrides, such as acetic formic anhydride (see below), are known. One or both acyl groups of an acid anhydride may also be derived from another type of organic acid, such as sulfonic acid or a phosphonic acid.ixed (or unsymmetrical) acid anhydrides, such as acetic formic anhydride (see below), are known.

Benzyl acetate has an ester functional group (in red), an acetyl moiety (circled with dark green) and a benzyloxy moiety (circled with light orange).Other divisions can be made. functional group is a moiety that participates in similar chemical reactions in most molecules that contain it. In turn the parts of the group are termed moieties. For example, methyl para-hydroxybenzoate contains a phenol functional group within the acyl moiety, which in turn is part of the paraben moiety.
