Oxime chemie
WebAn oxime is one in a class of chemical compounds with the general formula R 1 R 2 C N O H, where R 1 is an organic side chain and R 2 is either hydrogen, forming an aldoxime, or another organic group, forming a ketoxime . Oximes can be formed by the action of hydroxylamine on aldehydes or ketones .
