The discussion centers on the equivalence of the names 4-Ethyl,3,3-Dimethyl Hexane and 3-Ethyl,4,4-Dimethyl Hexane, concluding that they refer to the same compound, with 3-Ethyl,4,4-Dimethyl Hexane being the preferred nomenclature due to the alphabetical priority of ethyl over methyl. Participants emphasize the importance of IUPAC nomenclature rules in organic chemistry, particularly in naming compounds correctly. The conversation also highlights the challenges of learning organic chemistry solely from textbooks, contrasting it with structured classroom instruction.
PREREQUISITESStudents studying organic chemistry, self-learners seeking to master compound nomenclature, and educators looking for effective teaching strategies in organic chemistry.
Do either names violate any nomenclature rules?symbolipoint said:Yes. Same. I am not sure if one of those names is more correct than the other, but they are the same.
That finishes the answer. The Ethyl is bigger than the Methyl, so counting ascendingly along the chain, 3-ethyl,4,4-dimethyl hexane.Krushnaraj Pandya said:Do either names violate any nomenclature rules?
shouldn't ethyl be given preference and a lower number since it comes first alphabetically?
Alright, thank you very much :Dsymbolipoint said: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.
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...symbolipoint said: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.
