[Closed] Chemistry definition needed please.

a fluid made from monomers (eg ethene gas?)

or.....

a solution of monomers

those are my two guesses, i'd dig out my chem textbooks but suspect that you have as easier access as me.

*I'm no chemist, but I did do chemistry A level a while ago!

Well polymeric is having multiple "mer"s, or repeating units. So monomeric will be a fluid consisting of molecules that are not made up of repeating units. I would guess.

[url= http://en.wikipedia.org/wiki/Monomer ]Wikipedia helps[/url] if you twig to break it down from monomeric to monomer...and apparently it's a polydimethylsiloxane which suggests to my (probably wrong) head that its a polymeric molecule (consisting of many dimethylsiloxanes)?

I would guess the same, a liquid made up of individual molecules, not a mixture of carbon chain lengths (like a fraction). I would guess the sperical shape of the cyclo, 8 methly group molecule would help with lubricity.

bravo!
yeah that all makes sense!
and well done it is about a simulation about a lubricant
let the blagging continue!

I would guess the sperical shape of the cyclo, 8 methly group molecule would help with lubricity.

Now THAT's the sound of a chemist!

bottom line is then that octamethylcyclotetrasiloxane is a monomeric fluid?
yes or no?

I would say yes is the answer.
I think (Chemistry degree modules over a decade ago!) that a monomeric fluid is NOTHING to do with the molecules being made of monomers, rather to do with the homogeneity of the liquid.
I would say that a monomeric liquid is composed of a consistent uniform molecule.
The molecule would have the same formula, but would also have the same branch structure and configuration. Also I think it would have the same number of double bonds etc and arrangement of CIS/TRANS components.

Please let us know the the proper answer when you find it.

[url= http://books.google.co.uk/books?id=7_FrhazRTgsC&pg=PA82&vq=monomeric&dq=monomeric+fluid&source=gbs_search_s&cad=0 ]Fluid Dynamics book[/url] explaining monomeric and polymeric fluids as being based on monomers and polymers as mentioned earlier?

OP- Shouldn't you have attended lectures explaining this?

I'd go with option 1, consisting of the same component. If it was option 2 consisting of monomers then it would be a simple yes/no answer on the structure of the molecule rather than the molecular dynamics.
