NOMENCLATURE PART 1  IUPAC system of Nomenclature  The basic criterion for naming a structure by IUPAC system is choice of a parent name of the basic carbon skeleton. Nomenclature of alkanes is fundamental to naming whole class of organic compounds because it helps us identify the basic carbon skeleton. General rules for IUPAC nomenclature : The IUPAC system is the most rational and widely used system of nomenclature in organic chemistry. The most important feature of this system is that any given molecular structure has only one IUPAC name and any given IUPAC name denotes only one molecular structure. The IUPAC name of any organic compound essentially consists of five parts, i.e. Word root  Primary Suffix  Secondary Suffix  Primary Prefix  Secondary Prefix Thus, a complete IUPAC name of an organic compound consists of the following parts : Secondary prefix +Primary prefix + Word root + Primary suffix + Secondary suffix Word root : It is the basic unit of the name. It denotes the numb
