WebOximes are the chemical compounds that belong to the class of imines, having the general formula of R 1 R 2 C=N O H. Where R1 is the organic side-chain whereas R2 is the hydrogen, which forms an aldoxime, or like another group of organic compounds such as ketoxime. The O-substituted group of oximes forms a very closely related group of compounds. In organic chemistry, an oxime is a organic compound belonging to the imines, with the general formula RR’C=N−OH, where R is an organic side-chain and R' may be hydrogen, forming an aldoxime, or another organic group, forming a ketoxime. O-substituted oximes form a closely related family of compounds. … See more If the two side-chains on the central carbon are different from each other—either an aldoxime, or a ketoxime with two different "R" groups—the oxime can often have two different geometric stereoisomeric forms … See more The hydrolysis of oximes proceeds easily by heating in the presence of various inorganic acids, and the oximes decompose into the corresponding ketones or aldehydes, and hydroxylamines.
