If something contains large amounts of cyclopentane and cyclohexane, what is it called? I'd like to know what is the something as well. It's a chemistry olympiad question for this year. See here, Question 3-g. Just let google translate it for you. I find some questions quite weird as well, but what can you do. Otherwise its pretty good.

4$\begingroup$ Flammable. Is this seriously an Olympiad question? I highly doubt it has a specific name that is well accepted. $\endgroup$– JoriDec 25, 2014 at 13:22

1$\begingroup$ Which Olympiad was this in? National or international. I don't recall the question $\endgroup$– bonDec 25, 2014 at 16:01

The most likely name would be naphthenes. It could also be called cycloalkanes.
Added:
Since the reference to the question is about the coal and oil production, the answer would be naphthenes. When the coal and oil were distilled, a layer (called naphthene) was removed which was found to contain mainly cyclopentane and cyclohexane.
I would complete the statement as:
If a fraction of distillate contains large amounts of cyclopentane and cyclohexane, it is called naphthene.

$\begingroup$ The answer should be much more concrete than this I assume. I need to replace the word something as well as figure out what it is. $\endgroup$ Dec 25, 2014 at 17:00

$\begingroup$ Thanks for the answer man, I have a nice teacher so I can consult it with her without a problem. Fortunately enough, in the next rounds inspecific questions such as this one dont occur, they are more practical. $\endgroup$ Dec 26, 2014 at 17:27

$\begingroup$ Also I suppose for better specification, I think it would be better like this: If a fraction of distillate from oil and coil contains large amounts of cyclopentane and cyclohexane, it is called naphthene. Surely not all fractions of distillates are called napthenes, right? $\endgroup$ Dec 26, 2014 at 17:31
