The numbers 200-900 would be confused easily with 22 to 29 if they were used in chemistry. khīlioi = 1000, diskhīlioi = 2000, triskhīlioi = 3000, etc. 13 to 19 are formed by starting with the Greek word for the number of ones, followed by και (the Greek word for 'and'), followed by δέκα (the Greek word for 'ten').
The prefix form is "carbamoyl-". e.g., HCONH 2 methanamide, CH 3 CONH 2 ethanamide. Amides that have additional substituents on the nitrogen are treated similarly to the case of amines: they are ordered alphabetically with the location prefix N: HCON(CH 3) 2 is N,N-dimethylmethanamide, CH 3 CON(CH 3) 2 is N,N-dimethylethanamide.

If four oxyanions are possible, the prefixes hypo-and per-are used: hypochlorite is ClO −, perchlorate is ClO − 4. The prefix bi-is a deprecated way of indicating the presence of a single hydrogen ion, as in "sodium bicarbonate" (NaHCO 3). The modern method specifically names the hydrogen atom.
The prefix "spiro" followed by a Von-Baeyer descriptor describes in the nomenclature of organic compounds ring systems linked by only one common atom, the spiro atom. If several spiro atoms are present in the molecule, the prefix "spiro" is provided with a prefix ("dispiro", "trispiro", etc.) corresponding to the number of spiro atoms.
