Document Summary
Common name for ketones are substituent groups listed alphabetically + ketone. Aldehyde functional group is given the #1 numbering location and this number is not included in name: aldehydes and ketones page 1. Screen clipping taken: 2/10/2017 3:44 pm: aldehydes and ketones page 2. Predict the products of oxidation and reduction of aldehydes and ketones and give the reagents required to perform these reactions. Double bond - consists of one pi and sigma bond. Carbonyls exist on its own in aldehydes and ketones. Reduction with hydride and addition to carbonyl group. Type of nucleophile h- (h with lone pair) Reagents which are common sources of hydride (h-): lialh4, nabh4: aldehydes and ketones page 3. Reagents which are common sources of hydride (h-): lialh4, nabh4 e. g. nucleophilic addition reaction, reduction reaction. Double bond electrons shift to oxygen (intermediate product, alkoxide) work-up reaction to isolate the organic product - perform an addition of.
