Unformatted text preview: onal planar or pyramidal. Where two atoms surround a central atom, the shape would either be
line ar or be nt.
It is difficult to represent three- dimensional structures, like molecules, on a flat piece of paper.
It is equally as difficult to look at a molecular structure drawn on a piece of paper and imagine what it would look
like in three- dimensions. With the help of a molecular model kit and a computer modeling program, you will be
able to visualize a molecule in three- dimensions. In this lab, you will use a computer program within WebAssign
that allows molecules to be rotated, just like you could manually rotate a model built with a model kit. You will
also be able to use the computer program to obtain experimentally determined measurements, such as bond
