A hydrocarbon is an organic compound made of nothing more than carbons and hydrogens. Double or triple bonds can form between carbon atoms and even for structures, such as rings, to form. Saturated hydrocarbons have as many hydrogen atoms as possible attached to every carbon. Hydrocarbons teach about alkanes, preparation of alkanes from unsaturated hydrocarbons, from alkyl halides, from carboxylic acids, physical and chemical properties of alkanes. Hydrocarbons topic gives knowledge about Alkenes, the nomenclature of alkenes, isomers, preparation of alkene using alkyne. Organic chemistry is the scientific study of the structure, properties, composition, reactions, and synthesis of organic compounds.
