EXPLOSION and FIRE CONCERNS dangerous fire hazard NFPA rating Health 2, Flammability 3, Reactivity 0 explosive reaction with lanthanide perchlorates and nitrogen-fluorine compounds reacts with water, steam, and acids to produce toxic and flammable vapors incompatible with chlorosulfonic acid, nitric acid, sulfur trioxide use foam, carbon dioxide, or dry chemical for firefighting purposes. 

Qualitative analysis NMR is one of the most powerful methods available for determining the structure of molecules. It identifies the number and type of protons and carbon atoms in organic molecules, for example, distinguishes among aromatic, aliphatic, alcohols, and aldehydes. Most importantly, it also reveals the positions of the nuclei in the molecule relative to each other. For example, NMR will distinguish between CH3—CHj—CHjOH and CH3—CHOH CH3. It does not provide the MW of the compound. NMR is also applied to compounds containing heteroatoms such as sulfur, nitrogen, fluorine, phosphorus, and silicon. 

The reactivity of fluorine compounds varies from extremely stable, eg, compounds such as sulfur hexafluoride [2551-62 ] nitrogen trifluoride [7783-54-2] and the perfluorocarbons (see Fluorine compounds, organic) to extremely reactive, eg, the halogen fluorides. Another unique property of nonionic metal fluorides is great volatiUty. Volatile compounds such as tungsten hexafluoride [7783-82-6] molybdenum hexafluoride [7783-77-9] ... 

Unsaturated fluorinated compounds are fundamentally different from those of hydrocarbon chemistry. Whereas conventional alkenes are electron rich at the double bond, fluoroal-kenes suffer from a deficiency of electrons due to the negative inductive effect. Therefore, fluoroalkenes react smoothly in a very typical way with oxygen, sulfur, nitrogen and carbon nucleophiles.31 Usually, the reaction path of the addition or addition-elimination reaction goes through an intermediate carbanion. The reaction conditions decide whether the product is saturated or unsaturated and if vinylic or allylic substitution is required. Highly branched fluoroalkenes, obtained from the fluoride-initiated ionic oligomerization of tetrafluoroethene or hexafluoropropene, are different and more complex in their reactions and reactivities.
