The resulting cycloalkanes are replaced by only one covalent bond in the ring. two pi diene bonds were replaced by 2 sigma bonds.
Organic chemistry is a branching of chemical scientific studies regarding the structure, properties, composition, reactions, and synthesis of organic compounds. Organic compounds are built mainly by carbon and hydrogen and can contain other elements such as nitrogen, oxygen, phosphorus, halogen, and sulfur.
This original definition of organic chemistry stems from the misconception that all organic compounds must come from living organisms, but it has been proven that there are some exceptions. Life is also very dependent on inorganic chemistry; for example, many enzymes that base their work on transition metals such as iron and copper, and teeth and bones whose composition is a mixture of organic and inorganic compounds. Another example is the HCl solution, this solution plays a major role in the digestive process of food that almost all organisms (especially higher organisms) use HCl solutions to digest food, which is also classified in inorganic compounds. Regarding the element carbon, inorganic chemistry is usually associated with simple carbon compounds that do not contain bonds between carbon such as oxides, salts, acids, carbides, and minerals. But this does not mean that there is no single carbon compound in organic compounds such as methane and their derivatives.
The Diels-Alder reaction is an organic chemical reaction between a conjugated diene and substituted alkenes, commonly called dienophiles, to form substituted cyclohexene. This reaction can work even if some of the atoms from the ring formed are not carbon. Some Diels-Alder reactions can be reversed; the decomposition reaction of the cyclic system is called the Retro-Diels-Alder reaction. This retro reaction is generally seen when analyzing the Diels-Alder reaction product using mass spectrometry. Otto Paul Hermann Diels and Kurt Alder first documented this reaction in 1928. In 1950 they were awarded the Nobel Prize in chemistry for their work. The Diels-Alder reaction is generally considered the "Mona Lisa" reaction in organic chemistry because it only requires a little energy to form a very useful cyclohexene ring.
