Discussion: In this exercise you will get practice drawing electron dot structures for organic compounds. Then you are going to build a model of the molecule you drew using colored balls for atoms that are bonded together by sticks. Each element has one particular color ball. Elements in the same family can generally use the same ball. Each hole in the ball represents one bonding place or lone pair. You will also determine the shape of the molecule around each central atom. Use your text as a reference for determining the shapes.

Question:

1. Compare your predicted bond lengths and angles, and those predicted by the program, to the actual measured values in the given table. Which modeling system gave better results? Explain any differences and limitations to the method you used for predictions
