6. Thermodynamics and Kinetics

For each set of reactive intermediates, rank them in order of reactivity (1 = most reactive).

(c)

Identify the more stable carbocation in each pair.

(a)

List the following carbocations in decreasing order of their stability.

Which carbocation is more stable?

b.

Draw resonance structures to identify which of the following is the more stable carbocation.

We show in Chapter 12 that C― Br bonds can break to give a carbocation and a bromide anion. For which of the organohalides (A or B) would you expect this process to be fastest? Explain.
