Consider the organohalides A and B, where C―I bonds can undergo bond cleavage to form a carbocation and an iodide anion. Predict which organohalide (A or B) would undergo this process at a faster rate. Provide an explanation for your answer.

Will reaction 1 occur faster than reaction 2? (Note: Because of hyperconjugation, the more substituted carbocations are more stable.)

Most compounds containing the benzyl group produce a peak at m/z 91 corresponding to the tropylium ion.

Explain why tropylium cation is very stable.

Which among the following carbocation species is the most stable?

Based on resonance stabilization, identify which of the carbocations below is more stable.

Determine which of the following carbocations is more stable.
