Multiple-choice questions may continue on the next column or page – Fnd all choices before answering. These are OPTIONAL practice problems and DO NOT COUNT towards your Fnal 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 ±riday 3/5.
