Question

IUPAC name for:

Answer 1

Does the ring take preference over finding the longest carbon chain? If not, my best guess is: 1,4-diethyl-2-ethylcyclohexane

Answer 2

1,4-dimethyl, not diethyl. The 1,4 chains are only 1-carbon long, but the rest is ok.

Answer 3

what you should do is make the total number be the smallest since there is no other function group. JFraser's answer is right, though I just thought it was a typing mistake. ^^

Answer 4

Since the rule is to give the preference to the group which is alphabetically first,it should be
1-ethyl-2,5-diethylcyclohexane.....
is it right????

Answer 5

@Sarkar I usually number so that the functional groups get the lowest set of numbers as possible, so I would go clockwise from where you have #2, getting 1,4-dimethyl-2-ethyl, but IUPAC is crazy that way. When I took organic, the prof would accept just about any name, so long as it was, as he called it, "unambiguous". I figure that both systems would work, and an organic chemist would know what you were describing if you used either of these 2 options.
