Iupac rules for alkane nomenclature. find and name the longest continuous carbon chain. identify and name groups attached to this chain. number the chain consecutively, starting at the end nearest a substituent group. designate the location of each substituent group by an appropriate number and name. This organic chemistry video tutorial provides a basic introduction into naming organic compounds. it explains how to write the iupac nomenclature of alkane.

Alkanes can be described by the general formula c n h 2n 2. an alkyl group is formed by removing one hydrogen from the alkane chain and is described by the formula c n h 2n 1. the removal of this hydrogen results in a stem change from ane to yl. take a look at the following examples. 3.4. naming alkanes. in earlier times, when relatively few pure organic chemicals were known, new compounds were named at the whim of their discoverer. thus, urea (ch 4 n 2 o) is a crystalline substance isolated from urine; morphine (c 17 h 19 no 3) is an analgesic (painkiller) named after morpheus, the greek god of dreams; and acetic acid, the. 2.2 nomenclature of alkanes. as it has been shown that the number of constitutional isomers increases dramatically as the number of carbons increases, it is impossible to give each structure its own common name, like isobutane. as a result, a systematic method with certain rules is necessary when it comes to naming organic compounds. Iupac nomenclature of alkanes. identify the longest continuous carbon chain as the parent chain. this chain determines the parent name (or last name) of the alkane. if there are two choices of the same length, then the parent chain is the longest chain with the greatest number of “branches”. the term substituent will be used from now on as.

Regulatory purposes, the preferred iupac name, or pin. 2 substitutive nomenclature substitutive nomenclature is the main method for naming organic chemical compounds. it is used mainly for compounds of carbon and elements of groups 13–17. for naming purposes, a chemical compound is treated as a combination of a parent compound. Simply put, aliphatic compounds are compounds that do not incorporate any aromatic rings in their molecular structure. the following table lists the iupac names assigned to simple continuous chain alkanes from c 1 to c 10. a common “ane” suffix identifies these compounds as alkanes. longer chain alkanes are well known, and their names may.
