Introduction The Cope rearrangement, named after Arthur C. Cope, is one of the best-studied pericyclic reactions. It represents a thermal isomerization of 1,5-dienes, which leads back to 1,5-dienes. The main product obtained is the thermodynamically more stable isomer. The prototype of the Cope rearrangement is the isomerization of 1,5-hexadiene, in which only the position of the bonds but not the structure is changed.

Electrostatics is the branch of electricity that studies the properties and behavior of electrical charges at rest. Here's a list of formulas about this content. Electrical charges Elemental electrical charge Electrical charge Electrization Friction electrification Both electrically charged bodies have equal modulus loads but opposite signals.

Alkynes: The reaction with water takes place at room temperature and was the most important production method for acetylene for a long time. The carbide process has now been replaced by the preparation from methane: Methane is subjected to pyrolysis at 1500 ° C (with short contact times). The reaction is endothermic, but exergonic at very high temperatures.

This overview page lists the learning units of the topic & 34; Series development of functions & 34; from mathematics in a meaningful order in terms of content. Powers series 20 min. Powers series are limit values ​​of polynomials and offer the possibility of approximating smooth functions.

Chemical bond: resonance energy of benzene To answer the question of whether complete delocalization via the ring affects the stability of the molecule, the heat of hydrogenation of benzene is compared with that of the hypothetical cyclohexatriene. The heat of hydrogenation of the cyclohexatriene molecule is determined by extrapolating the results for cyclohexene ( -120 kJmol-1) and 1,3-cyclohexadiene (-230 kJmol-1).
