* 1. Draw reaction coordinate diagrams for dissociative, associative, and interchange mechanisms. Label the intermediate and/or...
Thermodynamics and kinetics of SN1, SN2, E1, and E2 mechanisms. 2. Draw the reaction coordinate diagrams of the following reactions according to the type of mechanisms given and include the following: a) Label the reactant, product, intermediates, and a drawing of the transition state of the rate determining step. If there are multiple E, label the largest E (5 pts) b) State if AG rx is <0 or >0 and make sure your diagram reflects the AGxn. (4 pts) Hint:...
Draw a labelled reaction coordinate diagram for the both SN reactions. Label the activation energy (free energy of activation) and give the approximate structures of the intimal state, the transition states, the intermediate and product at the correct points along the reaction coordinate. Also, can you decide on the basis of the kinetic expression whether the t-butyl chloride-hydroxide ion reaction proceeds by a one-step or a two-step mechanism? Explain why observed kinetic expression is consistent with the mechanism you chose.

1. Draw all of the constitutional isomers that are formed in each elimination reaction and label the mechanism as E2 or E1. a. 2-bromo butane reacts with methoxide b. 1-chloro-1-ethyl 2 methyl cyclopentane reacts with water 2. For which reaction mechanism are each of the following statements true? Mechanism S1, S2, E1 or E2. A statement may be true for one or more mechanisms a. The mechanism involves carbocation intermediates b. The mechanism has two steps C. The reaction rate...
Descriptions of enzyme mechanisms often contain the terms
reaction intermediate, transition state, and transition state
analogue. The terms intermediate and transition state both describe
chemical species along the reaction pathway, but there are
important distinctions between the two. Transition state analogues
are often used in enzyme mechanism studies. Match the phrases to
the term that they describe. Scroll down to see all the items.

5. Professor Karl von Fildenshmirtzen is studying a transition metal ligand exchange reaction as follows below and is attempting to determine whether or not the mechanism is associative or dissociative (RDS rate-determining step): Dissociative X RDS + Associative L RDS X + a. Describe how Professor Fildenshmirtzen may distinguish between these two mechanisms using an Eyring plot. b. The AS for the reaction was determined to be negative. Which mechanism is operative?
Problem 2 (10 pts) Circle the bromocyclohexane derivative that most likely corresponds to the reaction coordinate diagram for the reaction shown below. Indicate the probable reaction type: Draw the major product of the reaction. Label point A as either a transition-state (TS) or an intermediate (Int). Label point B as either a transition-state (TS) or an intermediate (Int). > Draw the structures of A and B. CH3OH reaction coordinate
