I can send you the pdf of the book if you want regarding IUPAC Nomenclature if you want. Just ask for it on niravbhattad24@gmail.com Nirraaav (talk) 03:21, 28 August 2020 (UTC)
 * Need to keep discussions on-wiki. Feel free to post a scanned page. As specific examples, I note that is called "4-propan-2-ylheptane" (parent-length 7 with 1 branch) not "2-methyl-3-propylhexane" (parent-length 6 with 2 branches). And  is "3-(bromomethyl)pentane" (parent-length 5 with 1 substituent) not "1-bromo-2-ethylbutane" (parent-length 4 with 2 substituents). In each case, using the maximum-length chain as parent is the first criterion, not maximizing the number of branches or substituents. Those names are generated from the structures using a toolkit that is documented to implement the current IUPAC rules. DMacks (talk) 12:10, 28 August 2020 (UTC)

 * What you cite is not at all what you wrote in the article. That answer and the IUPAC rule P-44.1.1 quoted talk about substituents "corresponding to the principal characteristic group (suffix)" (as clearly stated in the second rule in our article) not "attached to the parent as you keep adding. Instead, you keep removing maximum chain-length altogether, a concept that is clearly rule P-44.3.2. Instead, the mistake is that our rules 1 and 2 are simply reversed, exactly the situation identified at the end of the stackexchange answer. DMacks (talk) 04:44, 29 August 2020 (UTC)

Rule P-44.3.2 is for deciding the seniority between different compounds and not for the seniority between parent chains. And also I wanted to let you know that in the example which you told before (4-isopropyl heptane) iso is a common name and is not accecptable for IUPAC.

Also see Rule P-45.2.1 in IUPAC Recommendations and Preferred names 2013 on Page Number 517
