Chemistry 130 is an introductory course in chemistry. There are no prerequisites for this course, and it is assumed that you have little or no background in chemistry. You should be able to handle basic algebraic manipulations, and you should have a reasonably good calculator that you know how to operate. This semester we will cover the first 12 chapters of the textbook, as well as some selected topics from other chapters. For more specific information on course administration, click on the syllabus link below.

Chemistry 235 is the first semester of a year-long course in organic chemistry (CHM 235/236). The prerequisite for this course is Chemistry 152. Several sections from CHM 151/152 are used in studying organic chemistry. For example, we will begin the course with a review of atomic and molecular structure concepts (from CHM 151) that will serve as a foundation for our understanding of organic molecules. We will use kinetic information (CHM 152) to help us understand and predict mechanisms in organic chemistry. If you do not have a good understanding of these topics, it would serve you well to review them. A more detailed look at course administration can be seen by clicking on the syllabus links below.

Have you ever wondered why ice floats on water? This phenomenon is perplexing since, in general, the solid form of a substance is more dense than the liquid form. Water violates this pattern, however, due to the strong hydrogen bonding interactions between hydrogen and oxygen of different water molecules. In liquid water, the molecules are hydrogen bonded to one another, but they are oriented in a "best fit" arrangement that minimizes space between molecules. When water freezes, however, a very orderly array of water molecules forms that creates more space between molecules. This can be seen in the representations below. The red balls represent oxygen atoms, and the grey balls represent hydrogen atoms. The greater space found in ice means that there will be fewer molecules per unit volume, and its density will be less than that of liquid water (representations courtesy of Mathmol at NYU).
