This print-out should have 35 questions.
Multiple-choice questions may continue on
the next column or page – find all choices
before answering.
These are OPTIONAL practice problems
and DO NOT COUNT towards your final
grade. Note: A table of VSEPR structures
and hybrid orbitals will NOT be provided at
the exam. You need to learn how to construct
it or memorize it. You may want to try the
VSEPR problems ”closed book” to see what
areas you may need to work on for the exam.
Although the due date time is set to 7 pm
3/10 (your exam time), the answers will be
available at 10 am on Friday 3/5. Make sure
you download a copy of the questions before
then.
