I agree that this molecule has 3 tertiary carbons but when you look at their answer i believe its wrong...the first one is the carbon on the ring that branches off (ill call that C-1) then the next one is C-2 and then C-4

They say the tertiary carbons are C-2, C-3, C-4...C-3 is secondary not tertiary so i have no idea what they are talking about here...someone please confirm this thanks

what edition do you have in my edition of april 08 it clearly explains it the first tertiary is on the ring the next tertiary is the next carbon and the next tertiary is two carbons over.

Mine looks like this

exactly Dr. green got it right thats what it should look like but in the back the answers have #1 placed in the middle of 2 and 3 haha, must be the old edition

Osmis wrote something for you in my thread.. haha

osims my edition has that too and it is correct!

Numbering starts on the functional group not on the ring itself

The carbon that holds the ring is not chiral. The rings is not substituted at all in the pic here,and therefore it will be two of the same molecules. According to that pic how is the carbon on th ring chiral.???

I don't think they are talking about chirality. They are talking about naming the structure...

I would name it as 1,3-dimethylpentylcyclohexane, but they are saying its wrong!

What do you think?

I would name it as 2-cyclohexyl,4-methyl,hexane

I would name it as 2-cyclohexy,4-methyl,hexane

I think you treat the ring as your "longest carbon chain" and treat the entire pentane coming off it as a substituent.

I would name it 1,3-dimethylpentylcycloheptane

I agree, I would also name it as 2-cyclohexy, 4-methyl, hexane because that way you have a longer chain.

you have hexane at the end and so do I...what do you mean by your chain is longer?

 

[Mstoothlady2012]

I disagree....

 

[klutzy1987]

Im pretty sure that you always name it the way that will have the most substituents, as long as the chains lengths are equal.

the correct name is 2-cyclohexyl-4-methylhexane dont get cofused with phenyl since this is not a benzene.
