MWF 9:00 Section – Bocknack CH 310M/318M Fall 2009 UTEID: Please submit to the correct slot in the collection box outside WEL 2.212!!! Last Name: First Name: Score: Graded Homework Problem #04 Deadline : 3:00 p.m., Monday, 9/14/09 LATE WORK WILL NOT BE ACCEPTED OR GRADED!!! This problem is worth a total of 20 raw points. Each correct answer is worth 2 points. The molecule shown below is rifampicin, which is a bactericidal antibiotic. Rifampicin is one component of a “drug cocktail” that is frequently used in the treatment of tuberculosis. In the line–angle structure given below, no lone pairs are shown explicitly. All atoms in rifampicin have a formal charge of zero, however. Arrows marked with letters point to various parts of the structure. These letters correspond to the questions below the structure. Answer each of these questions, writing your response in the appropriate box.
