VSEPR is a model used to predict shapes of molecules. Electron pairs repel each other, and adopt an arrangement that minimises repulsion. To find the shape, a Lewis structure can be drawn, or use the following method (assumes single bonds only): N A M E O F S H A P E & B O N D A N G L E N o . o f b o n d i n g & l o n e p a i r s VSEPR & THE SHAPES OF MOLECULES L I N E A R - 1 8 0 ˚ 2 b . p .

    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.
