Some questions to examine in this chapter are: 1. Why are we interested in shapes? 2. What role does molecular shape play in life? 3. How do we determine molecular shapes? 4. How do we predict molecular shapes? Two Simple Theories of Covalent Bonding Valence Shell Electron Pair Repulsion Theory Commonly designated as VSEPR Principal originator R. J. Gillespie in the 1950’s Valence Bond Theory Involves the use of hybridized atomic orbitals Principal originator L. Pauling in the 1930’s & 40’s Overview of Chapter The same basic approach will be used in every example of molecular structure prediction:

    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.
