CH2FCF3 is technically 1,1,1,2-Tetrafluoroethane.
There's no reason I can see that Tetrafluoroethane couldn't equally refer to CHF2CHF2 which is 1,1,2,2-Tetrafluoroethane.
All the early google hits for Tetrafluoroethane are for 1,1,1,2-Tetrafluoroethane.
I added an note that the formula was for the 1,1,1,2 form to the article (remove it if not relevant). Is any of this material relevant enough to put in the article? RJFJR 00:36, Feb 13, 2005 (UTC)
