Question

[ORGANIC CHEMISTRY]
How would you guys name two cycloheptane placed as borromean rings.

Answer 1

See attachment to see what I mean

Answer 2

I would use bicyclo nomenclature.

Answer 3

yea but that does not explain the fact that the 2 rings ain't linked with covalent bonds... they are not link at all... just traped.

Answer 4

But it doesn't look like they're attached in the picture. It looks like simply two cycloheptanes.

Answer 5

I trid to draw it so good i could :P

Answer 6

Well, in a solution, you have to remember that molecules are free floating. They are not in a solid state and are able to move about freely and crash into one another which might explain why they are in that manner.

Answer 7

Like this

Answer 8

and the molecule do exsist.... acording to my prof

Answer 9

I'm sure that the molecule does exist. I'm not saying it doesn't, but my argument would be that, assuming they are in liquid state, they are able to crash into one another, causing bonds to be broken and new bonds to form within itself.

Answer 10

in a bottle of water, molecules are free floating, able to crash and break bonds and create new ones with other molecules is what I'm trying to explain.

Answer 11

if no bond exists then they cannot be put in one nomenclature per se. but you can always make up a name just to sound cool

Answer 12

So this molecule is from now on named.... molecule-WithOut-Name-1 or just WON1

Answer 13

There most be some way to name it...

Answer 14

you can use the prefix pseudo

Answer 15

Hmm think the gold book by IUPAC could have info?

Answer 16

maybe...

Answer 17

they cannot be interlocked permanently

Answer 18

abbot check my chem question

Answer 19

Okie dokie :)

Answer 20

where is your chem Q? Lol

Answer 21

Found it...

Answer 22

I have to log-in to my school database to be able to read the contents of that

Answer 23

same here, but atleast i found something that can give a hint.

Answer 24

But think it could be named cycloheptane[2]catenane

Answer 25

it should work

Answer 26

but if they do not function as a whole, it doesn't matter

Answer 27

does that occur naturally?

Answer 28

Engineered I would say,

Answer 29

or perhaps 1 in a 10^10

Answer 30

2,6-diformylpyridine
