Temple University - Department of Chemistry CHE 3302 - Spring 2013 Problem Set#7 Due 4/2/2013 1) Consider the hybridized orbitals associated with the sp 3 configuration (eqn 10.3 in Atkins). Show that h 1 and h 2 are orthogonal. 2) Calculate the bond orders for N 2 + , N 2 , and O 2 . 3) The overlap integral for the H 2 + molecule is Sketch S 12 versus R/a 0 . Where is the overlap integral a maximum and minimum. What is the value of S 12 at an equilibrium separation of 1.06 A? 4) Consider an hybrid orbital expressed as h=s+2 1/2 p z where s and p z are hydrogenic orbitals. Write this wavefunction out using the expressions for the relevant hydrogenic orbitals. What is the wave function in the xy plane? + + = - 2 2 0 0 12 3 1 o a R a R a R e S

    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.
