Fluoroalcohols are organofluorine compounds consisting of an alcohol functional group with at least one C-F bond. These compounds often have distinctive solvent properties.[1]
Perfluoroalcohols
[edit]Most primary and secondary perfluoroalcohols are unstable, for example trifluoromethanol eliminates hydrogen fluoride, forming carbonyl fluoride.[2] This reaction is reversible.[3]
- CF3OH → COF2 + HF
Stable perfluorinated alcohols include nonafluoro-tert-butyl alcohol ((CF3)3COH) and pentafluorophenol (C6F5OH).
Partially fluorinated alcohols
[edit]Numerous partially fluorinated alcohols are known and have useable stabilities. Trifluoroethanol and hexafluoroisopropanol are used as solvents in research.[4] Fluorotelomer alcohols are precursors to perfluorocarboxylic acids. Pirkle's alcohol is used a chiral shift reagent in nuclear magnetic resonance spectroscopy.

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
