Use the Molecule Shape simulator (http://openstaxcollege.org/l/16MolecShape) to explore real molecules. On the Real Molecules tab, select H2O. Switch between the “real” and “model” modes. Explain the difference observed.
3) Determine whether CH3CI is polar. To do this, you must: draw the
3D structure of the molecule, use arrows to indicate polar bonds, and
either use an arrow to indicate the net dipole moment or state that the
molecule is non-polar.
A model for SiH4 is shown in the chem3D window. SiH4 has tetrahedral geometry.
