Uses of Alcohols Ethanol CH₃CH₂OH Ethanol is a solvent its a widely safe solvent so used to dissolve many organic compounds that are insoluble in water especially for medicine to extract active constituents from inert parts of crude drugs . Part 4: Reactions of Alcohols; Substitution . Rxns. Reactions of Alcohols. Combustion. General eq’n for an alcohol combusting completely in oxygen:. C. n. H. (2n+1). OH(l) + (2n+1)O. 2. (g) . nCO. and how to identify them. 2. Classification. Primary. : carbon with –OH is bonded to one other carbon. Secondary. : carbon with –OH is bonded to two other carbons. Tertiary. : carbon with –OH is bonded to three other carbons. Properties & Synthetic Preps. Hydroxyl groups in natural compounds.. Alcohols. Naturally occurring p. henols: a . hydroxyl group directly attached to an aromatic ring.. Phenols. The –OH of an alcohol. Definition. Nomenclature. Cyclic form of sugar. Optical isomerism. Glycosidic. link. Polysaccharides. Carbohydrate derivatives. Defination. Carbohydarte. are . polyhydroxy. . aldehydes,polydroxyketones. 9-4. Organic esters are derivatives of carboxylic acids.. Inorganic esters are the analogous derivatives of inorganic acids.. Organic and Inorganic Esters from Alcohols. 9-4. Alcohols react with carboxylic acids to give organic esters.. Learning Objectives:. Know the general formula for alcohols.. Be able to name alcohols.. Describe the shape of alcohols.. Classify primary, secondary, and tertiary alcohols.. Describe the physical properties of alcohols.. Alcohol . – alkyl chain attached to an –OH. . R-OH. Phenol . - aromatic attached to an –OH. Nomenclature. 1. Name the longest chain of carbons which includes the carbon with the hydroxyl group.. Higher Supported Study . Week 3 – Part 2 . Chemistry of Cooking – Key Areas. Shapes of Proteins. Denaturing of Proteins . Flavour and Aroma Molecules. Aldehydes and Ketones. Tests to differentiate between Aldehydes and Ketones. PHENOLS. Alcohols and Phenols. Alcohols contain an OH group connected to a . a. saturated C (sp. 3. ). They are important solvents and synthesis intermediates. Phenols contain an OH group connected to a carbon in a benzene ring.
