Question
Chapter 22, Problem 37P
Interpretation Introduction
Interpretation: The mechanism for the following reaction has to be proposed.
Concept introduction:
- Catalyst: Substance which helps in increasing the rate of a particular reaction without getting consumed in the reaction.
- Intramolecular catalysis: A catalysis where catalyst is a part of the molecule that undergoes the reaction promotes the reaction in a species.
- Intramolecular nucleophilic catalysis: A catalysis where catalyst is a part of the molecule that undergoes the reaction promotes the reaction in a species by acting as a nucleophile.

Complete the following reaction and propose a mechanism
Hydroxylamine, H2NOH, has both an OH functional group and an NH2 functional group, so it can feasibly undergo reaction with a ketone or an aldehyde to produce either an acetal or an imine-like compound called an oxime. (a) Draw each of these mechanisms for the reaction of hydroxylamine with acetone. (b) Which is the major product? Hint: Which step decides the outcome?
c) Write a detailed mechanism for the following transformation:
