Unformatted text preview: EPR or hybridization. However, our
predictions are simply approximations because other factors influence the structure of real molecules. In this lab,
you will compare the bond angles and bond lengths predicted from theory to the experimentally determined
values. You will then be asked to explain differences that occur between the experimental values and the
theoretical values. Equipment

The Chem- Tutor model kit was designed by Professor Samuel G. Levine for use by his organic chemistry
students at North Carolina State University. Atoms : Atoms are represented by jacks that have one, two, three
or four pegs coming out. Each peg represents an electron region (or electron group). The electron regions
(groups) can be single bonds, double bonds, triple bonds or lone pairs. In general, black jacks are used for
carbon, blue for nitrogen, red for oxygen, white for hydrogen and...
