285 Chemistry 1A F11 11.21.11 Dr. Shaka Course Code 40000 Orthonormal Hybrids You can verify on your own that " A 2 dxdydz all space ### = 1 = " A " B dxdydz all space ### = 0 Just follow the rules for the integrals of the 2 s and 2 p functions. The four hybrid orbitals are said to be orthonormalized .

286 Chemistry 1A F11 11.21.11 Dr. Shaka Course Code 40000 Other Hybrid Combinations We can take an s and a p , ( sp ), an s and two p s ( sp 2 ), sp 3 as we saw, to get linear, trigonal planar, and tetrahedral orbital geometries. In more advanced courses you will see that we can make trigonal bypyramidal and octahedral geometries with dsp 3 and d 2 sp 3 hybrids (hard to draw/see!). You can match to orbital geometries of VSEPR just by counting two through six hybrid orbitals.

287 Chemistry 1A F11 11.21.11 Dr. Shaka Course Code 40000 sp Hybridization (Linear) If we combine the 2 s with one 2 p , either with the same sign of with opposite sign, we get a pair of hybrid orbitals along a line. These would describe the bonding in a molecule like H-C C-H.

    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.
