- Consider the attached E2 reaction What happens to the reaction rate with each of the following changes?[1] The solvent is changed to DMF. [2] The concentration of −OC(CH3)3 is decreased. [3] The base is changed to −OH. [4] The halide is changed to CH3CH2CH2CH2CH(Br)CH3.

- According to the rules for reasonable mechanisms, the E1 reaction shown here should undergo a 1,2-hydride shift. However, the same product is produced regardless of whether the rearrangement occurs. Br H20, heat (a) Draw the mechanism that includes that carbocation rearrangement. (b) Draw the mechanism that does not include the rearrangement. (c) Experimentally, how can we use 13C isotope labeling to determine whether the rearrangement occurs? In other words, can a 1ºc atom in the substrate be replaced by a 1°C atom so that the E1 products would depend on whether the rearrangement takes place? (d) How can we use deuterium isotope labeling to determine whether the rearrangement occurs?arrow_forwardA student adds NBS to a solution of 1-methylcyclohexene and irradiates the mixture with a sunlamp until all the NBS has reacted.
