What is the relative reactivity of 2° vs 1° hydrogens in the free radical bromination of n-butane if the ratio of 1-bromobutane to 2-bromobutane formed is 7:93?
The relative reactivity of the 1°: 2°: 3° hydrogens of (CH3)3CCH2CH3 in free radical chlorination is 1: 3.8: 5.0. Provide the structure of each monochlorination product, and estimate the relative amount of each in the mixture of monochlorinated products.
Draw all monochlorination products expected from reaction of chlorine with 3,4-dimethylhexane. Circle the major product.
Which of the following statements is the best statement of the Hammond Postulate?
A) In an endothermic reaction, the transition state is closer to the reactants in structure.
B) In an exothermic reaction, the transition state is closer in energy to the products.
C) Related species that are similar in energy are also similar in structure.
D) The structure of the transition state in an organic reaction is always modeled on the structure of the reactants leading to that transition state.
E) Transition states are molecular species of finite lifetime whose properties can be probed through free radical reactions.
