Aldehydes and Ketones

When carbon is double bonded to an oxygen, you know have the polarity of the bond and the second bond reactivity to work with. You should anticipate high reactivity. The carbon is positive and the oxygen is negative. The carbon will react with negative things while the oxygen will react with positive things. You should also expect that non-polar materials will be less likely to react with this polar double bond as apposed to an alkene which is non-polar.

Orientation

To begin with, you should review Markovnikov's rule for addition reactions to alkenes. Next, review the oxidiation of alcohols. Lastly, review the imine formation chemistry discussed in chapter 15 lectures. Aldehydes and ketones are big in organic and biochemistry. These biochemistry applications are important. Be ready.

Lectures

Lecture will continue to integrate the reactivity of functional groups and show parallels to biochemistry. This week we introduce the carbonyl functional group in the form of the aldehyde and ketone. There is a relationship her to sugar chemistry and amino acid synthesis through transaminations.

The overview page communicates to the students expectations (learning objectives) and what they should do in the learning module (activities). Information, especially activities, should be clear and concise. Giving too much information on this page can create "cognitive overload" and confusion.
