Carbocation Stability Practice Problems
(a) Arrange the following carbocations in decreasing order of stability. (b) Determine which carbocation is likely to form first. (c) Which carbocation is expected to undergo the fastest reaction with a bromide ion (Br–)?
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.
