How does cycloalkane's locant numbering work?
Q. for cyclohexane, is locant#1 on the very top? or the next one to the right? And how do we number cycloheptanes(octanes,non anes, etc.)? Is there a consistent rule?

A. in a cycloalkane whether cyclohexane, cycloheptanes, etc withno substituents, all carbons are equal so it doesnt matter where you place locant #1. If you do start attachin substituents, lets say an hydroxyl group on top and a methyl group to the left or right, that's when number becomes important and in this case the locant with the OH would be #1 and the methyl #2, hope this helps

How do you name a cycloalkane attached to an alkene?
Q. How do you name a cycloalkane attached to an alkene? Say cyclohexane is attached to a Decene...and the attachment of the the double bond is at no. 2 carbon and cyclohexane is attached to no. 2 carbon as well. So the name would be ? "2 - cyclohexyl - 2 - decene" Would you drop cyclo- and just put the -hexyl, or not?
Asked by Marcus - Thu Dec 11 11:06:58 2008 - - 3 Answers - 0 Comments
A. No, you can't really drop the "cyclo" because that's different than just plain hexyl.

How to determine cycloalkane and alkane?
Q. How do we test these two hydrocarbons?
Asked by SCieNCe - Mon Aug 10 10:26:28 2009 - - 2 Answers - 0 Comments
A. Theoretically you can burn it with excess O2 and from the volume of the output, work out the mole of CO2 and H2O. Then you can see if the molecule is CnH2n (cycloalkane) or CnH(n+2) (chain alkane)

Are there alkyl groups in a ring (cycloalkane)?
Q. ok so i know that alkyl groups are basically an alkane minus a hydrogen (alkyl = alkane - H) e.g. CH3, CH2CH3, CH2CH2CH3, etc..but in a ring there are only CH2 groups, so are they counted as alkyl groups as well?? or methylene groups..i'm really confused..
Asked by sarisha <3 - Tue Apr 15 20:56:18 2008 - - 2 Answers - 0 Comments
A. No, the ring is the base, any CH groups that may branch off of it are the alkyl groups. Just name the ring as a cycloalkane.

why is the BOILING POINT of cycloalkane HIGHER than n-alkane?explain.?
Q. i found this in my book but i hav my explaination which can show it's the inverse. please verify my answer. my explaination: cycloalkanes have smaller surface area than n-alkane, thus their van der waal's forces between molecules are lesser, lesser energy needed to overcome them hence they hav lower boiling point.

A. It's been a long time since I took organic.. or any science but that sounds right to me. Instead of just looking at one molecule you should also look at it overall. A bulky chain alkane does not fit together easily with another bulky chain. Cycloalkanes can pack together easier which causes van der waals with the other cycloalkanes causing a higher boiling point.

Q. which will have a higher boiling point? alcohol or cycloalkane? Why?
Asked by kernal - Mon Oct 5 20:38:50 2009 - - 2 Answers - 0 Comments
A. Alcohols have hydroxy groups (-OH) on them somewhere. I'm assuming by "alcohol", you mean ethanol, the most common alcohol. The hydroxy group in this molecule allows it to hydrogen bond to other molecules of ethanol, forming a "lattice" of hydrogen bonds and bringing up ethanol's boiling point. A Cycloalkane, however, does not have such hydrogen bonding capabilities. An alkane is a molecule composed entirely of carbon and hydrogen, containing no double bonds. The only forces holding these molecules together in liquid state are dispersion forces (or Van Der Waals interactions). Therefore, ethanol has the higher boiling point.
