oximes are obtained by reaction of aldehydes or ketones and hydroxylamine in a weakly acid medium. The mechanism is analogous to that of imine formation.

Asymmetric aldehyde and ketone oximes exhibit Z/E isomerism depending on the position of the hydroxyl group.

The imines and hydrazones (which we will discuss below) also present this characteristic.
