IUPAC nomenclature problem

[Krushnaraj Pandya]

Homework Statement

My only doubt while solving a larger problem is whether 4-Ethyl,3,3-Dimethyl Hexane and 3-Ethyl,4,4-Dimethyl Hexane equivalent?

 

[symbolipoint]

Yes. Same. I am not sure if one of those names is more correct than the other, but they are the same.

Yes. Same. I am not sure if one of those names is more correct than the other, but they are the same.

Do either names violate any nomenclature rules?
shouldn't ethyl be given preference and a lower number since it comes first alphabetically?

That finishes the answer. The Ethyl is bigger than the Methyl, so counting ascendingly along the chain, 3-ethyl,4,4-dimethyl hexane.

difficult to read but might help as a review for some things: https://en.wikipedia.org/wiki/IUPAC_nomenclature_of_organic_chemistry

The two different names are the same compound but the one starting with ethyl is the better name.

Alright, thank you very much :D

Learning to name organic compounds was easy from the books available back then as a student. Modern day textbooks I assume are just as good. That wikipedia article showed much legalistic descriptions of how to name compounds, but further down was guidance for what was needed for your example compound.

I took a look at it and found learning nomenclature of ethers and esters very useful (not given in my textbook) but it was quite tiring to read and keep all the rules in mind while reading ahead...although I have encountered a more intriguing nomenclature problem which I'm about to post

Students in school and using both their in-class instruction and assigned textbook readings deal with far fewer rules at the start, and then are given just enough of needed nomenclature instruction as their studies progress. Like I said, much easier to handle the learning that way.

the trouble with me is I can't learn inside a classroom at all due to various factors. However I am adept at learning from a textbook extremely well, so this forum is a blessing for me and the only way I don't get stuck anywhere while contemplating a problem. I'm not sure if this will work for organic chemistry though...
