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"
