I am trying to name the attached hydrocarbon, and I'm stuck between two different ways of thinking.

On one hand, it looks like there is a heptane chain with a cyclohexane attached to Carbon 4. If it were named in a manner similar to the way any other substituted alkane is named, it would be called 4-1,3,5-cyclodipentylheptene. (if my naming skills are correct)

On the other, I also thought to look for the longest possible carbon chain and treat the leftovers as add ones to this backbones. In this case, the longest chain would be 9 and there is a propyl group attached to the 4th carbon. (4-propylnonane). Which of these two options makes more sense?

The structure you drew cannot exist.  You have five bonds to a carbon.

Hey!

thats not cyclohexane but benzene ring, also known as phenyl if its name as a side group.

Hi Jason,

I do agree with both Astrokel and Yggdrasil that the structure drawn in wrong and the carbon ring is that of Benzene.

However, assuming that you meant to draw a Cyclohexane ring, the compound should be names as as :

4-Cyclohexylheptane

[Astrokel]

i think it is dipropylcyclohexane, but not sure if it exists.

[Jason2103]

The five bonds attached to the 4th carbon confused me also.

I had never heard of Benzene before, but when I looked it up on wikipedia it looks exactly like the structure in the question.

rahulghosh, when you say if I had meant to draw a Cyclohexane ring, do you mean essentially the same ring structure without the double bonds? If that was the csae, then your way of naming it would seem to make sense. Thank you everyone for your help.

[Astrokel]

yes cyclohexane is a hexagonal ring without double bond, i think 4-cyclohexylheptane suggests another compound.

[Jason2103]

My apologies everyone, I realize now that I made a HUGE mistake in drawing the diagram. On the fourth carbon where there is the cyclic hydrocarbon, there is a vertical line coming off of the 4th carbon going up, and the cyclic is attached to that. Hopefully everyone gets the idea, and will be able to more accurately help name it now.

[Astrokel]

(1-propylbutyl)benzene or 4-phenylheptane or heptan-4-ylbenzene(IUPAC name, if im not wrong)

Do you know how to go about naming?

[Jason2103]

I know how to name most Alkanes, Alkenes and Alkynes, but I'm struggling with some of the cyclic hydrocarbons. If it is just a cyclic with double bonds or, say, a methyl or ethyl group coming off the side, I can name that, but I was confused about this one since it is both cyclic and there is an alkane backbone.

an aromatic hydrocarbon with a 7 carbon compound side chain....

[rahul2ghosh]

(1-propylbutyl)benzene or 4-phenylheptane or heptan-4-ylbenzene(IUPAC name, if im not wrong)

Do you know how to go about naming?

Hi Astrokel/ Jason,

Thanks for providing the correct structure. The correct IUPAC name should be Phenyl-4-heptane. Also refer to the attached diagram, as i have tried to make it self-explanatory.

sorta looks like a virus.

i agreee looks like a veroid to me....
