Unformatted text preview: Chemistry 310N Dr. Brent Iverson 2nd Midterm March 29, 2007 NAME (Print): _____________________________ SIGNATURE: _____________________________ Please Note: This test may be a bit long, but there is a reason. I would like to give you a lot of little questions, so you can find ones you can answer and show me what you know, rather than just a few questions that may be testing the one thing you forgot. I recommend you look the exam over and answer the questions you are sure of first , then go back and try to figure out the rest. Also make sure to look at the point totals on the questions as a guide to help budget your time. Note: You must have your answers written in pen if you want a regrade!!!! Please print the first three letters of your last name in the three boxes For synthesis problems GO FOR PARTIAL CREDIT EVEN IF YOU DO NOT KNOW THE ENTIRE ANSWER!!!WRITE DOWN WHAT YOU DO KNOW IS IN THE REACTION SEQUENCE SOMEWHERE. YOU WILL GET PARTIAL CREDIT IF IT IS CORRECT 10 9 8 7 6 5 4 3 2 (26) (34) (19) (18) (29) (19) (19) (25) (17) (21) (14) (7) (16) (16) (18) (6) (304) 11 1 Page Points Total T Score HW 12 13 14 15 16 Honor Code The core values of the University of Texas at Austin are learning, discovery, freedom, leadership, individual opportunity, and responsibility.
