For each of the following molecules or ions (Showing your work on pages 8(D) - 5 to 8(D) - 7):
1.
determine the total number of valence electrons;
write the Lewis structure;
give the electron pair Steric Number (or Coordination Number) of each central atom;
indicate the type of hybrid orbitals used by each central atom:
make a clear sketch of the structure;
indicate all important bonds angles3B
describe the shape using one or two appropriate words such as linear, bent, trigonal planar,
trigonal pyramidal, T-shaped, tetrahedral, square planar, see-saw, trigonal bipyramidal,
square pyramidal, octahedral, etc., for each central atom.

Don't forget to indicate charge on Lewis structures by enclosing the structure in square
brackets, with the charge outside the bracket (upper right).
2.
For each of the following make a labeled orbital diagram (on p. 8(D) - 8) showing how different
orbitals overlap to form bonds. Mark the bond angles on the diagram. Be sure to provide some
indication of the three dimensional shape for each.
a. CH3 - CH2 - CH2 - CH3
b. CH2 = CH - CH = CH - CI

c. H3C - C = C- CH = CH - Br
3.
Make models (p. 8(D) - 8) of cis-1,2-dibromoethylene and trans-1,2-dibromoethylene. Sketch
these two structures. How can one be converted to another? Why does this not occur at room
temperature?
