Pauling Electronegativities in a Flash

Lewis dot diagrams, VSEPR theory and Pauling electronegativities can be used to predict the polarities are small molecules, generally with fewer than ten atoms. Once the polarity of several molecular substances is known, it is usually possible to indicate the relative order of their boiling and/or melting points with some confidence.

Use Adobe Flah to draw faithful animations, with perspective, of the following bonding arrangements: AX and AX2 (linear), AX2 (V – shaped), AX3 (trigonal planar), AX3 (trigonal pyramidal) and AX4 (tetrahedral). Craft a short flash animation illustrating the polarity of these bonding arrangements.
