Hint:The IUPAC nomenclature refers to the systematic approach as per the recommendation of the International Union of Pure and Applied Chemistry. We can draw the structures of the given compounds by keeping in mind the nomenclature rules.
Complete step by step answer:
Basically in chemical nomenclature, the organic chemistry nomenclature IUPAC is a method of organic chemical compounds as recommended by the International Union of Pure and Applied Chemistry. The IUPAC name of the organic compound essentially consists of three parts which are stem name, prefix and suffix.
Moreover, the aim of the nomenclature IUPAC program is to create an international standard for designating compounds to promote communication. The main purpose of this system is to give a unique name to each structure. As per this rule, the first thing that is taken into consideration is the longest continuous chain. After that the numbering should be done from the end which is close to the highest priority group (functional group). Now, let’s draw the structures of the given alkyl groups:
1.Iso pentyl
IUPAC name- 3-methylbutyl
2.Tent-pentyl
IUPAC name- dimethyl propyl
3.Isohexyl
IUPAC name- 4-methylpentyl
4.Neohexyl
IUPAC name-3,3-dimethylbutyl
Note:
The IUPAC nomenclature guidelines are not always followed by chemists because some compounds have very long and extremely tedious names. Sometimes, the IUPAC names are simpler than older names for e.g. ethanol rather than ethyl alcohol.
