Properties of Alcohols and Phenols Experiment #3 Objectives: To observe the solubility of alcohols relative to their chemical structure‚ to perform chemical tests to distinguish primary‚ secondary and tertiary alcohols‚ and a color test for phenol. Introduction The general formula of an alcohol is ROH in which the R is an aliphatic hydrocarbon group. Alcohols may be looked upon as derivatives of water‚ HOH. One hydrogen of water is substituted by an alkyl group‚ R. Like water‚ alcohols show hydrogen

REACTIONS OF HYDROCARBONS Vanessa P. Manibpel De La Salle University - Dasmariñas ABSTRACT Five substances namely Hexane‚ Eugenol‚ Unknown hydrocarbon 1‚ Unknown hydrocarbon 2‚ and Acetylene gas was used for the selective reactivity of hydrocarbons to functional group tests; Bayer’s test‚ Bromine test light‚ Bromine test dark‚ and Tollen’s test. In Bayer’s test‚ only Acetylene‚ Eugenol and Unknown hydrocarbon 2 reacted positively and the rest retain the purplish color of KMnO4. On the other hand

Abstract Tamoxifen‚ most commonly sold under the brand name Nolvadex‚ is the most widely used drug in the treatment of breast cancer during both early and late stages. It belongs to a class of drugs known as SERMs (Selective Estrogen Receptor Modulators). SERMs work by blocking the estrogen receptors in breast cells to prevent any binding with estrogen. It is consumed orally as a tablet or as a liquid (Anon.‚ 2017). The following paper discusses the discovery of Tamoxifen‚ its laboratory synthesis
