Predict the geometry around each highlighted atom.

5. Draw the # and molecular orbitals for the discrete and localized T bonds in the following structures. Indicate any polar- ization these bonds may have in your diagram through the shapes of the discrete bonding and antibonding orbitals. e 6. Show any plausible resonance structures for the molecules given in Exercises 1 and 5. If there are no plausible resonance structures, indicate this (note that the molecule corresponding to letter A is the same in each problem). 7. Discuss the hybridization in the C-C and C-H bonds of cyclopropane, given that the H-C-H bond angle is 118°. withara --- totrachlorida b dingl A. B. C. D. 3

s it possible to draw a resonance structure with the lone pair? What is the hybridization of the heteroatom? Draw a valence bond orbital diagram to show the location of the lone pair (you do not need to draw any orbitals to show s bonds). In what orbital are the electron pairs located?
