Document Summary

Molecular shape, lewis structures tell us how atoms are connected in a covalent molecule or ion, can be used to predict molecular shape, determines how molecules function, essential to drug design and other biochemical. 2d representations of 3d structures: wedge and dash notation, line, bond drawn on the plane of the page, wedge, bond projecting toward you (1)out of the page, dashed, bond going away from you (1)behind the page. Isomers: deinition, have the same number and type of atoms, but difer in how the atoms are arranged, have dif. properties, types, structural isomers (aka constitutional isomers, have the same chemical formula, but have dif. atom connectivity (1)dif. Lewis structures: stereoisomers, have the same chemical formula, but difer in arrangement (same atom connectivity) (1)geometric isomers (2)optical isomers (a) enantiomers (i) two non-superimposable mirror images (b)chirality (i) Handedness (a) right glove doesn"t it the left hand (i) mirror image object is dif. from original object.
