Lecture 1, 'Atoms, orbitals & bonding topics', may seem long, but it includes a quick review of what you should remember from inorganic chemistry and ensures that everyone begins the course with the same foundation knowledge about atoms and bonding. This lecture then moves on to orbital hybridization and molecular geometry. For reference, see Chapter 1 of Daley & Daley.
I've divided the lecture up into slide sets that cover a single topic so that each can be downloaded individually. If you want to bring the slides to class, download them via the links below and print them out. Printing two slides per page will save you some paper. Homework questions are organized by topic as well and are posted in the column of buttons the the right. (Note that buttons with asterisks* are mandatory assignments.) The questions listed for each topic are due at the class meeting after we've finished that topic. Topics are organized by number and title and should be simple to follow. I've also posted a set of examples that we can use as extra practice problems in class, during office hours or during help sessions. They are also organized by topic. You may want to print these out and bring them to class. A practice quiz offers you more opportunities to check you understanding and preparedness for the exam.
