Molecular Shapes and Optical Activity

• Unpolarized light (normal light) runs in all directions

• Polarization is confining the vibration of a wave to one direction

• Polarizer: a filter that only allows light waves in a particular direction to pass

• Various shapes will absorb and deflect the polarized light in different ways

Molecular Shapes Why do molecules take on these shapes?

Molecular Shape

VSEPR Theory• valence shell e- pairs repel each other

electrostatically so as to minimize repulsive forces• lone pairs are bulkier (occupy more space) and repel

bonded pairs of e- more strongly

Task:Build models of molecules in tables from p. 243-245 in text. Draw 3-D diagrams, write shape name and label bond angles for each molecule.
