Experiment 6 Testsfor Aldehydes and Ketones Both aldehydes and ketones have carbonyl group and thus have similar reactions due to this functiona group. The C-o double bond consists of a -bond and a bond. The electrons situated above an below the carbonyl plane are exposure, making the carbonyl bond reactive. Oxygen is more electronegative than carbon and the C-O bond is polar, more negative on...
