1. Azobisisobutyronitrile (AIBN) is an azo compound (a compound with a NEN double bond) that is often used as a radical initiator. Upon heating, AIBN liberates nitrogen gas to produce two identical radicals. a. Please provide a reasonable mechanism for the formation of the radical and nitrogen gas. (2 points) NCCH HọG CHỊ HCN, XE NC 1 NON NO CHE CH b. Explain why the radical generated from AIBN is so stable. Be sure to use a minimum amount of words and a drawing to support your answer. (4 points) c. Explain why the following azo compound is not useful as a radical initiator. (3 points) HC CHI 2. One strategy for the synthesis of complicated polycyclic ring systems involved radical-mediated cyclization processes. For example, when the following radical is generated, it undergoes a spontaneous cyclization to produce two new radicals. Propose a plausible mechanism to account for the formation of each tricyclic ring system. (6 points total) Oran - B
