P2p to oxime
WebMechanism: The first step in the process is formation of an oxime from the aldehyde or ketone, which occurs in a sequence similar to formation of imines and hydra zones. In the first step, the nitrogen adds to the carbonyl carbon (Step 1, arrows A and B) followed by proton transfer (Step 2, arrows C and D).

WebJun 5, 2016 · In oxime, nitrogen is attached to carbon by a double bond; and in nitroso, nitrogen is attached to oxygen by a double bond. Now it is known that greater the difference in the electronegativity values, stronger is the bond. This property makes the nitrogen carbon double bond stronger hence making oximes more stable than nitroso.
