Christen Thomsen Barfoed. Christen Thomsen Barfoed (16 June 1815 – 30 April 1889) was a Danish chemist credited with the development of a method to detect monosaccharide sugars in a solution, now known as the Barfoed's test. [1] [2] Barfoed is also credited with having introduced systematic chemical analyses in Danish agricultural sciences. [3]

The [BAr F 4] − anion with four fluorinated aryl groups distributed tetrahedrally about a central boron atom. Tetrakis[3,5-bis(trifluoromethyl)phenyl]borate is an anion with chemical formula [{3,5-(CF 3) 2 C 6 H 3} 4 B] −, which is commonly abbreviated as [BAr F 4] −, indicating the presence of fluorinated aryl (Ar F) groups.
Tollens' reagent tests for aldehydes (known as the silver mirror test) The Zeisel determination tests for the presence of esters or ethers; Lucas' reagent is used to distinguish between primary, secondary and tertiary alcohols. The bromine test is used to test for the presence of unsaturation and phenols.
