:Br: slow Br fast a) Write the rate law for the reaction above. b) Draw curved arrows showing electron movement in each step, and label the step as nucleophilic attack, proton transfer, leaving group, or rearrangement. c) How would the reaction rate be affected if the iodide concentration were doubled? d) How would the reaction rate be affected if the 2-bromo-2-methylpentane concentration were doubled?
How does each of the following changes affect the rate of an E2 reaction? a.tripling [RX] b.halving [B:] c. changing the solvent from CH3OH to DMSO d.changing the leaving group from I− to Br− e. changing the base from −OH to H2O f.changing the alkyl halide from CH3CH2Br to (CH3)2CHBr
Associate the reaction mechanism with the indicated characteristics of the base or nucleophile. Assume that the electrophile bears a good enough leaving group. E2 1. Species is a strong nucleophile but a weak base Could be SN1 or E1, depending on the electrophile's structure 2. Species is a weak nucleophile but a strong base 3. Species is a strong nucleophile and a strong base SN2 Could be SN2 or E2, 4. Species is a weak nucleophile and a depending on the electrophile's structure weak base >
