WebThe inductive effect strongly stabilizes the fluoroform anion and plays a lesser role as we move down the series. Steric \ electron repulsion effects strongly stabilize the iodoform anion and plays a lesser role as we move up the series. Said differently, only one effect stabilizes the fluoroform (inductive) and iododform (steric) anions, but ...

Trifluoromethane or fluoroform is the chemical compound with the formula CHF3. It is one of the "haloforms", a class of compounds with the formula CHX3 (X = halogen) with C3v symmetry. Fluoroform is used in diverse applications in organic synthesis. It is not an ozone depleter but is a greenhouse gas. See more About 20M kg/y are produced industrially as both a by-product of and precursor to the manufacture of Teflon. It is produced by reaction of chloroform with HF: CHCl3 + 3 HF → CHF3 + 3 HCl It is also generated … See more CHF3 is used in the semiconductor industry in plasma etching of silicon oxide and silicon nitride. Known as R-23 or HFC-23, it was also a useful refrigerant, sometimes as a replacement for chlorotrifluoromethane (CFC-13) and is a byproduct of its manufacture. See more • McBee E. T. (1947).

A ton of HFC-23 in the atmosphere has the same effect as 11,700 tons of carbon dioxide. This equivalency, also called a 100-yr global warming potential, is slightly larger at 14,800 for HFC-23. The atmospheric lifetime is 270 years. See more • International Chemical Safety Card 0577 • MSDS at Oxford University • MSDS at mathesontrigas.com See more WebZinc sulfate, 10%. C1. A = Good resistance, B = Acceptable with limitations, C = Not recommended. 1 = Possible crystallization, blockage, or possible coat peeling. 2 = Swelling of plunger, possible peeling. 3 = Acid vapors (better resistance with lower concentration) 4 = Risk of damage, softening or discoloration of external parts through vapors. how many wii games were there
