PLEASE EXPLAIN ME HOW TO SOLVE ANY IUPAC PROBLEM

Dear student
Please find the solution to the asked query:
 
  • Branched chain hydrocarbons


 

Rules for the Nomenclature of Branched Chain Alkanes

  • Longest chain in the molecule is identified (called parent or root chain).

    Numbering is done is such a way that the branched carbon atoms get the lowest possible numbers.



    The names of alkyl groups attached as a branch are then used as prefix in the name of parent chain. The position of the substituents is indicated by the appropriate numbers.


 If two or more identical groups are present, then prefix   di  (for 2), tri (for 3), tetra (for 4) are used.

 
  • Numbers are separated by commas.

  • Lower number is given to the one coming first in the alphabetical listing.



    Carbon atom of the branch that attaches to the root alkane is numbered 1.
