... The deceleration by substituents in the 6th position is stronger (ρ = 3.14, r = 0.981) than in the 5th position(ρ = 0.80, r = 0.999). In the opposite reaction of cyclization of β-ureido acids [11] substituents accelerate the reaction, the effect of βsubstituents being the stronger. Thus the greater ...

... This step is also when the electrophile binds to the ring (i.e. governs the location of substitution). The enhanced rate and substitution pattern for toluene can be explained by considering the structures of the intermediate sigma complexes for substitution at each of the different positions. The RD ...

... with dissolved oxygen, the reaction releases a significant amount of heat. However, when the reaction occurs in mitochondria during respiration, it produces very little heat. Explain why the heat evolved is much less in mitochondria. According to the First Law of Thermodynamics, energy can be transf ...
