This article discusses the mechanism of electrophilic addition reactions in organic chemistry. The features of halogenation and hydrohalogenation of unsaturated hydrocarbons are analyzed in more detail. In addition, the material tells about regioselectivity in the interaction of asymmetric molecules, the influence of electron-donor and electron-withdrawing substituents on the formation of the final reaction product

If you look at the chronology of the study in chemical science of the ability of atoms of various elements to interact with each other, we can single out the middle of the 19th century. At that time, scientists drew attention to the fact that hydrogen compounds of oxygen, fluorine, nitrogen are characterized by a group of properties that can be called anomalous

Today we will look at the features of organic chemistry. In particular, a representative of the class of alcohols - allyl alcohol. Allyl alcohol, also called propen-2-ol-1. Refers to simple monohydric alcohols, is a colorless liquid with a characteristic odor

The article discusses the main groups of hydrocarbons that make up oils: paraffins, naphthenes, arenes. Formulas of examples of hydrocarbons of all groups and chromatograms of mixtures of paraffins are given. Methods for studying the composition of oil are described. The sources of oil hydrocarbons are considered. The concept of relic and converted hydrocarbons is given
