This unit looks more in depth at molecular compounds to see how they are bonded together by looking at Lewis structures. These structures provide information about the types of bonds (single, double, or triple) as well as the connectivity of atoms. By knowing the Lewis structure, we can also predict the three-dimensional geometry of an individual molecule.

Very informative, and includes application of lessons like lab experiments. Great lecturers and lessons, but sometimes lack information for full understanding (for beginners). Would recommend!

由 WL 提供2016年7月23日

This is a great course. The primary feature is the number of worked and practice problems. Instead of memorizing, one learns by doing. Short of being in the lab, this is the next best thing.
