Comment: Fair homework, easy predictable exams, not a bad lecturer, interesting material. Not awesome, but nothing to complain about. Tilley isn't great with homework questions at office hours, but is helpful for lecture or conceptual questions. The book is awesome, just be able to do the problems at the end of the chapter (solution manuals are online) and you can get an A fairly easily.

Comment: Professor Tilley is a good lecturer, and I do find his classes intriguing. He would tell interesting stories about famous chemist and it was really funny. His assignments are very helpful for exams. I've never been to any office hours so I cannot tell his helpfulness. The exams are really fair. As long as you practice with problem sets, go to gsi review sessions, do problems in the book and past midterms, I think you are fine. Understanding Point groups and MO is the most important thing in Chem104A

Comment: Tilley's not a bad guy. He's not inspirational, but he does no harm. I have no feelings towards inorganic chemistry after taking this class. There are two major concepts which dominate the final and the midterms, group theory and molecular orbitals. Do whatever you can to understand them, the GSI's are a very good resource for this. Try to get them to do problems for you if you are confused. The class is slow paced and descriptive rather than rigorous. Be prepared to bring your own enthusiasm.

Comment: Chem 104a has been one of my most favorite classes in the Chemistry department. I thought 4a was awesome, 4b sucked, and wasn't the biggest fan of ochem (112A), so I was very much looking forward to this class. The first month or so is more or less review, but then the class takes a steep turn when group theory is introduced. It is an unorthodox concept and requires a very good geometric grasp in order to recognize symmetry elements. That being said, I thought that was one of the coolest parts of the class, especially the portion on bonding and different ways of looking at it. The class has some mathematical rigor, but nothing compared to 120A. The class presents a much more in-depth picture of MO and Valence bonding theory, as well as the SALC method using group theory. It presents a pretty good picture of mixing of orbitals based on symmetry, providing a much more clear picture of bonding. Many of the concepts in this class blew my mind, such as how using the SALC point of view SF6 only has 4 bonds, and 2 localized electron pairs, to yield a bond order of 2/3. The exams were pretty fair, but were clearly written by the GSIs, James and Billy. The first midterm was ridiculously long and hard, resulting in an average in the mid 50s or so. The second midterm was conceptually much more difficult as it had mainly bonding theories and group theory, but the exam was much more fair. The last month or so, the class delves into solid state chemistry, which had a lot of random facts and memorization. The final was quite fair but beware, group theory makes quite a big appearance all over the final. We never got to know how we did on the final however. The psets in this class are quite worthless, and are written by the GSIs. They are quite hit or miss, ranging from ridiculously easy, to insane amounts of tedious busy work. They do not help prepare for the exam much. The boom M&T is quite good for most of the class, and so is DG. Both the GSIs don't seem to care much about the class, nor are they that good at answering questions. On the other hand, Prof Tilley is quite good at answering questions and is quite thorough. He is quite a clear lecturer, although a bit boring at times, considering how long the lecture is. Billy is the more laid back of hte GSIs. Homework is arbitrarily graded again, where they pick a problem or 2 at random and grade them, and they are graded separately by the GSIs so people with same answers often get different scores. The class material is very interesting and worthwhile, but the class needs to be run better

Comment: This class consists of two midterms and a final. HW was a good indicator of the questions on the exams. I think the gsi wrote the exams. Professor Tilley is a good lecturer and answers questions that students raise in class. The material is pretty interesting to learn. We first reviewed vsepr and then moved on to group theory. Then, for the second midterm it was focused towards mo and acid/base. And then the last few weeks were on structure of solids and some trends in the periodic table. For group theory, the Vincent book is really helpful. Otherwise, MT and DG were good supplements for the class. The gsi's James and Billy were pretty helpful. They had weekly review sessions as well as reviews before the exams.

Comment: Tilley is a really good instructor. His voice is so soothing. His exams are quite difficult (probably written by GSI). The GSI sucks, but he is a very good instructor.
