I would like to know about the common prefixes namely iso- and neo- which are used in organic nomenclature. I just wanted explanations about using these, I mean when and where to use these and what do these mean?
Oh, I see. When would these prefixes not be used in organic nomenclature?
These prefixes are not used in cases where the molecule does not contain a branching structure, or where the branches are not significant enough to require a specific naming convention. For example, in butane or pentane, there is no need to use these prefixes because there is no branching in the molecule.
