n, iso and neo are no longer used in the systematic nomenclature, but still frequently in trivial names and in laboratory jargon. The prefix n describes a straight-chain carbon skeleton without branches, whereas iso describes a branched skeleton, without specifying any further details
The prefixes sec (from "secondary") and tert (from "tertiary") refer to the number of additional side chains (or carbons) connected to the first butyl carbon. The prefix "iso" or "iso" means "isolated" while the prefix 'n-' stands for "normal". Butan-2-yl (sec-butyl) group is chiral. The carbon atom at position 2 is a stereocenter.
Exceptions are cyclo, iso, neo, and spiro which are considered part of the name and therefore not italicized or hyphenated. Substituent groups are also considered part of the name. In former versions of the IUPAC recommendations, names were written with a capital initial letter.
