Since free ions are more reactive than ion pairs, the rate of propagation is faster in more polar solvents. [6] [10] The size of the counterion is also a factor. A smaller counterion, with a higher charge density, will have stronger electrostatic interactions with the carbenium ion than will a larger counterion which has a lower charge density. [2]
The hydroperoxide anion is a more reactive nucleophile than neutral hydrogen peroxide. Consequently, oxidation accelerates as pH increases toward the pK a of hydrogen peroxide and hydroperoxide concentration climbs. At pH higher than 13.5, however, oxidation does not occur, possibly due to deprotonation of the second
In the first six periods this does not make a difference to the relative order, but in the seventh period it does, so the seventh-period elements have been excluded. (In any case, the typical oxidation states for the most accessible seventh-period elements thorium and uranium are too high to allow a direct comparison.) [ 11 ]
These reactions are exothermic and the rise in temperature is usually in the order of the reactivity of the different metals. [5] If the reactant in elemental form is not the more reactive metal, then no reaction will occur. Some examples of this would be the reverse.
where A and B are reactants C is a product a, b, and c are stoichiometric coefficients,. the reaction rate is often found to have the form: = [] [] Here is the reaction rate constant that depends on temperature, and [A] and [B] are the molar concentrations of substances A and B in moles per unit volume of solution, assuming the reaction is taking place throughout the volume of the ...
NHO-CO 2 adducts are of particular interest due to their reactivity; NHOs are able to form zwitterionic NHO-CO 2 adducts that are 10-200 times more reactive than NHC-CO 2 adducts. [11] These adducts are then able to do many reactions, such as carboxylative cyclizations of propargyl alcohols and cycloadditions with aziridines to yield ...
First, kinetic studies of reactions between diazomethane and various ketones have shown that the overall reaction follows second order kinetics. [7] Additionally, the reactivity of two series of ketones are in the orders Cl 3 CCOCH 3 > CH 3 COCH 3 > C 6 H 5 COCH 3 and cyclohexanone > cyclopentanone > cycloheptanone > cyclooctanone.
