The structural prefix s- or sec- (for secondary-) and t- to tert- (for tertiary-) maybe incorporated in a
name to designate a specific secondary or tertiary alkyl group, respectively. If no isomeric alkyl group of the same
classification are possible. These prefixes are underlined italics and separated from the rest of the name by hyphens.
The alkyl group represented by formula
