IUPAC Names of Organic compounds (2)

Click For Summary
SUMMARY

The discussion centers on naming organic compounds using IUPAC rules, specifically focusing on the compound identified as 3-ethyl-2-methylpentane. Participants emphasize the importance of selecting the longest carbon chain with the most substituents and acknowledge that in some cases, multiple chains yield the same name. For comprehensive learning, resources like Khan Academy are recommended for understanding IUPAC nomenclature.

You select the chain with more no. of substituted carbons. If that gives you more than possible answer, either you apply the other rules (for functional groups if any), or in some cases, it doesn't matter which chain you select. All give the same compound. So, which chain(s) have more no. of substituted carbons?
 
Well, it appears to be the chain number (2), OR (3). Is there a place where I can find all the important rules for naming alkanes in one location?
Thank you for your help.

Exactly. And hence, it doesn't matter in this case. It's 3-ethyl-2-methylpentane.
It's hard to find all in one place, though a simple Google search of the IUPAC nomenclature will render you the most important ones. It's better to just learn them as they come across. Still, you can see the Khan Academy videos.
