Hi I'm new her and I have a question about isomers. I am ok with drawing isomers of alkanes, but I am not entirely sure about "equivalent carbon atoms". For example, in my lab manual it asks to draw the isomers of C3H5Br3, and how many equivalent carbon atoms there are in each isomer. Is equivalent carbons referring to 1°, 2°, 3°, etc. or is it something else. I have googled a more general search of carbons in alkane substitution reactions, and a large amount of the results were NMR spectra stuff which is not being discussed in my class (survey o-chem). Anyway, I apologize if my post is done incorrectly. Thanks so much!
