INTRODUCTION O Carbonyl compounds have functional group called carbony C and there are two types of carbonyl compound that is aldehydes and ketones. Both aldehydes and ketones have general formula, CnH2nO O O General structure of aldehyde is R-C-H whereas ketone is R-C-R'.Aldehyedes are named by using the suffix-AL while for ketones, it was named by using the suffix-ONE. Carbonyl compounds can be prepared from the following reactions. 1. Oxidation of alcohol 2.oth aldehydes and ketones have general formula, CnH2nO O O General structure of aldehyde is R-C-H whereas ketone is R-C-R'.
