PPT-Aldehydes and

ketons Formaldehyde Acetaldehyde Chloral hydrate Benzaldehyde Aceton Acetophenone It contains variety of chemical compound including benzoate ceosol benzaldehyde y terpineol. 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 . In General. Fragrant odors. Basic building block of housing materials. Hormones. Digestion. Vision. 2. In General. Carbonyl group. C=O. Aldehydes. RCH=O. Formyl. Ketones. RC=OR’. 3. Nomenclature. The Civet Cat is the original source of . civetone. , a sweet and pungent ketone used as a fixative in perfumery. Aldehydes and ketones are found in many fragrant odors of many fruits, fine perfumes, hormones etc. some examples are listed below.. ,-Unsaturated Aldehydes and Ketones. 18-8. Conjugated unsaturated aldehydes and ketones are more stable than their unconjugated isomers.. Enones, or . ,-unsaturated carbonyl groups, are stabilized by resonance.. Before you can learn about aldehydes and ketones, you must first know something about the nomenclature of carboxylic acids since many of the names of aldehydes and ketones are derived from the names of the corresponding carboxylic acids.. 17-4. Laboratory syntheses of aldehydes and ketones use four common methods.. Oxidation of alcohols:. Ozonolysis:. Hydration of the carbon-carbon triple bond y. ields enols that tautomerize to carbonyl compounds.. The Civet Cat is the original source of civetone, a sweet and pungent ketone used as a fixative in perfumery. Aldehydes and ketones are found in many fragrant odors of many fruits, fine perfumes, hormones etc. some examples are listed below.. 1. Chapter 16. Aldehydes & Ketones:.
