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 IUPAC nomenclature of organic chemistry, for example, uses the numerical prefixes derived from Greek, except for the prefix for 9 (as mentioned) and the prefixes from 1 to 4 (meth-, eth-, prop-, and but-), which are not derived from words for numbers.
In chemistry, a number of prefixes, suffixes and infixes are used to describe the type and position of the functional groups in the compound. The steps for naming an organic compound are: [5] Identification of the most senior group. If more than one functional group, if any, is present, the one with highest group precedence should be used.
Prefixes, suffixes, and infixes are known as organic chemistry affixes. These affixes provide details about the molecule's structure, such as the quantity of carbon atoms, the kind of carbon-to-carbon bonds, and the existence of functional groups. [2] The following are a few typical additions in organic chemistry: Prefixes

A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
The IUPAC definition of an "organometallic compound" includes boron, silicon, arsenic, and selenium, so this title guideline also applies to organoboron chemistry, organosilicon chemistry, etc. [15] For consistency this is extended even to obvious nonmetals, e.g. organoxenon chemistry.
