Nomenclature
The names of acyl groups are derived typically from the corresponding acid by substituting the acid ending -ic with the ending -yl as shown in the table below. Note that methyl, ethyl, propyl, butyl, etc. that end in -yl are not acyl but alkyl groups derived from alkanes. IUPAC nomenclature is recommended but rarely used.
