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. Starter:. Use molecular models to make various alcohol molecules. Keywords:. Esterification, elimination, ester, dehydration. Learning Objectives. A.

Alcohols are derivatives of hydrocarbons in which 1 or more of the hydrogen atoms has been replaced by a hydroxyl (-OH) . Alcohols and Ethers. Alcohols. Alcohols are compounds whose molecules have a hydroxyl group attached to a saturated carbon atom. The saturated carbon may be that of a simple alkyl group . Examples. Or the saturated carbon may be connected to an . Definition. Nomenclature. Cyclic form of sugar. Optical isomerism. Glycosidic. link. Polysaccharides. Carbohydrate derivatives. Defination.

(CH₃CH₂OH). :.  . -Ethanol is a solvent: it’s 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. .
