Bocknack CH 310N Spring 2010 UTEID: Please submit to the correct slot in the collection box outside WEL 2.212!!! Last Name: First Name: Score: Graded Homework Assignment #02 Deadline : 2:00 p.m., Friday, 1/29/10 LATE WORK WILL NOT BE ACCEPTED OR GRADED!!! This assignment is worth a total of 40 raw points. Each question is worth 20 points. 1. (20 points) Propose a mechanism for the overall transformation shown. Use “normal” curved arrows to show movement of pairs of electrons. Be sure that your mechanism shows all important reaction intermediates. Unless otherwise indicated, if an intermediate is a resonance hybrid, it is only necessary to draw the structure of the most important contributing resonance structure. Make sure you show all lone pairs and nonzero formal charges! To help you get started, the reactants involved in the first step of the mechanism are shown below the overall transformation.
