WebThere are plenty of reactions in which the more stable product ( thermodynamic) is also formed faster ( kinetic ), so do not assume that every reaction fits this mould! The reaction mechanism The first step is … WebThermodynamic reaction control or kinetic reaction control in a chemical reaction can decide the composition in a reaction product when competing reactions lead to different …
WebThe kinetic product comes from a Diels–Alder reaction, while a cheletropic reaction makes a more thermodynamically stable product. The cheletropic pathway is used more because it makes to a more stable five-membered ring adduct. The scheme below shows the difference between the two products. WebA reaction under kinetic (or rate) control will yield predominantly: l) The most stable product. 11) The product that can be formed in the fewest steps lI) The product whose formation requires the smallest free energy of activation IV) The product with the greatest potential energy b) II djv e) V N. Which of the following is true of benzene?
WebThe reaction produces the corresponding sulfine through a hetero-Diels–Alder reaction under kinetic control (≤ -60 °C), but, under thermodynamic control (≥ -40 °C), the reaction produces the corresponding sulfolene through a cheletropic reaction. The activation enthalpy for the hetero-Diels–Alder reaction is about 8 kJ/mol smaller ...
