Results and Observations: A. To determine the shapes and polarities of a number of molecules using the VSEPR model. With the help of the software program Spartan, the agreement between the VSEPR model and the quantum mechanical calculations produced by Spartan will be examined. And lastly a drug molecule is to be designed that will believably bind with a hypothetical receptor site. B. This experiment was divided into three parts; A, B, and C. Part A: 1. Spartan quantum mechanics calculations: a) NH3 Distance from: H – N = 1.012 Ȧ b) H – H = 1.653 Ȧ Angle: H – N – H = 109.47˚ c) N – H – H = 35.26˚ d) After Optimizing the Molecule: Distance from: H – N = 1.003 Ȧ e) H – H = 1.665 Ȧ Angle: H – N – H = 107.21˚ f) This angle was smaller than the angle measured earlier. Dipole: The dipole moment pointed towards the lone pair and had a magnitude of 1.92 Debye.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
