(organic chemistry) Of, relating to, or being a ketone.
The carbonyl group is not ketonic in character since it yields neither an oxime nor hydrazone.
compounds containing an oxy in addition to an aldehydic or ketonic group) undergo both condensation and oxidation when treated with phenylhydrazine, forming compounds known as osozones; these are of great importance in characterizing the sugars (q.v.).
The remaining oxygen atom is aldehydic or ketonic, for the sugars combine with hydrocyanic acid, hydroxylamine and phenylhydrazine.
p. 2207); and by the action of ammonia on a-halogen ketonic compounds (W.
It unites with aldehydes to form esters of ketonic acids, and with aniline yields anilido-acetic acid.
