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?

Sure, I can help you with that. The prefix "iso-" is used to denote the presence of a branching structure in a molecule. It is used when one of the substituent groups on the carbon chain is itself a chain. For example, isobutane contains a branched chain of three carbon atoms. The prefix "neo-" is similar to "iso-" in that it denotes a branching structure, but the difference is that neo- refers to a branched structure that contains a quaternary carbon atom in the center. An example of this is neopentane.
