Alcohol dehydrogenation can proceed via a carbocation intermediate. Which, if any, of the following statements accurately describe carbocation behaviour? There may be more than one correct answer. They are exceedingly reactive They are typically easily formed under very gentle reaction conditions They exist for extended periods of time and may be isolated from solution Stability is determined by the number of substituents on the carbocation Solution Alcohol dehydrogenation can proceed via a carbocation intermediate. This reaction goes through SN1 pathway. Carbocations are more reactive than neutral compounds. stabilitty of carbocation depends on the number of substituents. + I effect and +R group stabilize the carbocation due to electron releasing effect. tertiary carbocation is more stable than primary carbocation. some time carbocations are isolated. This is possible for stable carbocation. but they can not exit extended period of time. answer: They are exceedingly reactive. Stability is determined by the number of substituents on the carbocation. .
