Modeling Lab

The purpose of this lab was to be able to better understand and recognize molecular structures and polarity.


HF



H2O2



CH3NH2



C3H8
























CH4


PROCEDURES:



1) build a model for each of the molecules listed on the data table on the back of this page.





2) Draw the tree-dimensional structure of each molecule table 1. Use solid lines to represent bonds in the plane of the paper, dashed lines for bonds that point back form the plane of the paper, and wedged lines for bonds that point out from the plane of the paper toward viewer.


3) Note the shape of each molecule in the third column of table 1, the bond angles in column 4, whether or not they will be polar in column 5, and whether or not they exhibit resonance structure in column 6.











From our experiment, we have observed and learned that there is much more to molecular shape than meets the eye. Some have double bonds or even triple bonds or many more pairs of electrons than you would have thought.

  1. Good job and good pictures. keep up the work with improving your format, especially the spots for the pics. good choices of molecules though

  2. diggin the colors =]]
    maybe add some pictures of the models
    nice job

  3. Nice Job more pics and lacking information

    Bye, have a good day

    LOL :)

  4. I would suggest making the pictures smaller. They seem to take up too much of the page. But other than that, it's a good start! :~)
