This reaction proceeds through a three-membered ring halonium intermediate. The first step involves arrows similar to the carbene reaction above plus an additional arrow showing the Cl-Cl bond breaking. The second step is SN2 at the more substituted carbon. 8) Complete the following reaction by adding curved arrows, intermediates, and the expected products.
