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
