Oxidation Number When elements combine to produce a compound‚ each element is assigned an “apparent” charge. This apparent charge‚ the charge an atom would have if both electrons in each bond were assigned to the more electronegative element‚ may be positive or negative. It is called the oxidation number or state of the element in the compound. Oxidation numbers are very useful in keeping track of what happens to electrons when various elements combine to form compounds. By remembering a few

Lab 5 Oxidation of an alcohol CHM2123 Introduction: Oxidation is a key reaction in organic chemistry. Oxidation of an alcohol can produce aldehydes‚ ketones‚ or carboxylic acids. One of the methods of oxidation is an aldol reaction through carbon-carbon bonds. The oxidation oxidizes primary alcohols to aldehydes and secondary alcohols oxidizes ketones. Tertiary alcohols are converted to the common oxidizing agents. Scheme 5.1: Aldehydes can be oxidized easily to carboxylic acids in aqueous medias

The Frege’s puzzle originates from Frege’s study of identity in his paper On Sense and Reference [Frege‚ 1892]. So far from the emergence of the Frege’s puzzle‚ philosophers have given many solutions‚ but there has not been a perfect one. Among these philosophers‚ although Frege and Russell did not solve the Frege’s puzzle perfectly‚ they still provided a good direction for future philosophers. This paper will analyze Frege and Russell’s solution to the Frege’s puzzle‚ with a description of the differences
