.8.6. Some halogen anomaly aspects are a. Problem 6. 1-chloroethene adds HI slower than ethene, and yields 1-chloro-1-iodoethane only. a. Draw the carbocation intermediate that forms for each reaction. b. Which carbocation would be more stable, based on relative reaction rates? Which factor induction or resonance) controls relative carbocation stabilities? What carbocation would have been formed if 1-chloroethene had yielded 1-chloro-2-iodoethane? Is this carbocation more or less stable than the 1-chloroethyl carbocation in a? d. Which factor controls relative reactivity for 1-chloroethene? Which factor controls reaction orientation? c
