✔ 最佳答案
Both p-cyclohexylnitrobenzene and p-nitrocyclohexylbenzene are the name of the below compound, in which a cyclohexyl group and a nitro group are attached to the para-position of a benzene ring.
However, p-cyclohexylnitrobenzene is correct, while p-nitrocyclohexylbenzene is incorrect. This is because the prefixes of the name are arranged in alphabetical order. The first letter of "cyclohexyl-" is "c" which is in front of "n", the first letter of "nitro-". Hence, "cyclohexyl-" should be written in front of "nitro-".
