Organic Chemistry Post-Lab: Aerobic Oxidation of an Alcohol Using a Cu(I)/TEMPO Catalyst System

identify all the components in the product mixture, 4-methoxybenzyl aldehyde, as identified by gc-ms data and draw structure of the molecular ion for each mass spectrum. Provide electron-pushing mechanism that rationalizes the generation of the base peak ion in the mass spectrum of the oxidation product.
