2814 C O OC OC Q1 Carbonyl compounds are formed by oxidation of alcohols a Which type of alcohol is oxidised to an aldehydeb Which type of alcohol is oxidised to a ketonec What compounds are. Aldehydes. The term Aldehyde come for the words . al. cohol . dehy. drogenation. . Preparation: Oxidation of primary alcohols according to the following equation:. Note: Oxidation can be considered as removal of hydrogens. Dr. Talat R. Al-Ramadhany. Introduction . Aldehydes are compounds of the general formula . RCHO. ;. Ketones are compounds of the general formula . RR´CO. . The groups R and R´ may be aliphatic or aromatic. . Aldehydes and ketones. Carbonyl Compounds. Contain the carbonyl group . C=O. . Aldehydes: . R may be hydrogen, usually a carbon containing group. Ketones: . R contains carbon. Short. forms. Structures of Aldehydes . Lecture 6. CARBONYL COMPOUNDS: . NUCLEOPHILIC ADDITION REACTION. ALDEHYDE.
