hederahelix: Sizeism in fic and society'Cis' is hostile? I remember being quite pleased the first time I became aware of 'cis' and related terms - it filled a lexical hole that I had not realized was there.
Weird passage of time at work today - doing really tedious stuff apparently makes the day fly by. Probably because I can devote a portion of my brain to pre-writing.

Date: 2009-07-01 17:09 (UTC)This is a long-chain hydrocarbon -- bunch of carbons bonded to hydrogens -- with a double bond in the middle (the R and R' just denote lots&lots of, like, CH3CH2CH2CH2CH2, so basically just a long stretch of hydrocarbon with no wacky stuff thrown in; I used R & R' because you can't use R twice unless it's the exact same chain. In retrospect it would've been easier to just use R twice, so good call me.) Now, when naming this hydrocarbon chain, the hydrogens aren't important, so we just ignore them. If you do that, you'll see that, going from one side of the double bond to the other, the R and R' are on opposite sides (because ignoring the hydrogens just means not putting them in the name; unless otherwise specified it's assumed that all open bonds on a carbon are filled by hydrogen). That makes this a trans double-bonded hydrocarbon.
This is another long-chain hydrocarbon with a double bond stuck in the middle. All of the other stuff I said up there goes, only here if you just look at R and R' they're on the same side. That makes this one a cis double-bonded hydrocarbon.
:D?
