A single ketone can also be converted to the corresponding alkene via its tosylhydrazone, using sodium methoxide (the Bamford–Stevens reaction ) or an alkyllithium (the Shapiro reaction ). Source: Internet
Beta-hydroxybutyrate is a reduced form of acetoacetate, in which the ketone group is converted into an alcohol (or hydroxyl ) group (see illustration on the right). Source: Internet
As a pyramidal bond geometry is forced upon the nitrogen atom by the ring strain, the resonance of the amide bond is reduced, and the carbonyl becomes more ketone -like. Source: Internet
Characterization An aldehyde differs from a ketone because of its hydrogen atom attached to its carbonyl group, making aldehydes easier to oxidize. Source: Internet
Exceptions to this rule are the unsaturated ketones such as methyl vinyl ketone with LD 50 of 7 mg/kg (oral). Source: Internet
