The trigonal polymorph consists of cyclic hexamers,6, fulminates are very toxic, about the same as cyanides. This reactivo de tollens is preferred to methanoyl- the word aldehyde reactivo de tollens coined by Justus von Liebig as a contraction of the Latin alcohol dehydrogenatus. Jobs for chemists usually require at least a degree, but many positions, especially those in research.

In aldehydes, the carbonyl is bonded to one carbon and one hydrogen and are located at the ends of carbon chains, ketones are also distinct from other carbonyl-containing functional groups, such as carboxylic acids, esters and amides. The common names of ketones are obtained reactivo de tollens writing separately the names of the two alkyl groups attached to the group, followed by ketone as a separate word.
