A set of questions to be used in General or Introductory Inorganic Chemistry as a review or “quiz” of shapes and polarities.
In answering these questions, a student will:
determine shapes of molecues;
determine polarity of bonds;
synthesize the information to determine polarity of molecules.
If you do not have a method of polling students online, you can use index cards for answers OR just have students write down answers.
I have used this set of automated response questions as a Gen Chem I review to start Gen Chem II. Since students complete Lewis Structures, Polarity of Bonds, VSEPR, and Polarity of Molecules at the end of Gen Chem I at QU, and we start with Intermolecular Forces in Gen Chem II, I need to review for those who either forgot or never learned the basics.
I plan to use this early in my Inorganic course this fall, since I have found some students don’t remember those basics at that level, either.
Using Automated Response System in PowerPoint lecture format.
Attached is a Word document with results from Gen Chem II (one section) in spring 2015. I was able to complete all shape and bond polarity questions and 3 of the molecule polarity questions on the first day after reviewing the course syllabus with the class.
