Unit 8 Quiz (50 points) If you can return this quiz by Tuesdaynoon, I will return them "instantly" so can you use it to studyfor the final---MD
Name _________________________
1. (10 ) Explain the difference between a "sigma" and a "pi"bond. Use and "s" atomic and a "p(x)" atomic orbitalto sketch the type of orbital overlap that represents a sigma bond. Usethe p(y) orbitals of two adjcent carbon atons two sketch the type ;of orbitaloverlap thet represents a "pi" bond.
2. (10 ) For each of the following electron-pair geometries, VSEPR Thoery, indicate what hybrid orbital set would give the same geometry. For example:"linear" = sp hbridized
a) tetrahedral
b) trigonal planar
c) octahedral
d) trigonal-bipyramidal
3. (15) Draw the Lewis structures for IF2 (- ) and IF2 (+) ions. Discussthe molecular geometry and the predicted F-I-F bond angle in each ion. Whatis the hybridization of the iodine in each case is required to give thepredicted molecular structures?
a) IF2 (- )
b) IF2 (+ )
4. (15) Draw the Lewis structures for each of the following and completethe "table"
| Lewis Structure | VSEPR geometry | Hybridazation of central atom |
b) H3O+
c) PCl5
d) HCN
