CEM 141: VSEPR
opposing formal charge groups - ANS-Transisomer

same side formal charge groups - ANS-Cysisomer

comparison method, keep count of e- - ANS-Formal charge

FC = Valence e- on free atom - # of bonds - non-bonded electrons - ANS-Formal charge
equation

an element forming an unusual # of bonds - ANS-Can tell if something has a formal charge if

valence shell electron pair repulsion theory - ANS-What does VSEPR stand for?

helps us figure out shape of molecule through lewis structure
- assume all centers of e- density repel each other
- minimum energy arrangement that the atom will naturally take up - ANS-What does VSEPR
do?

Angle of 180, sp hybridization - ANS-Linear shape

angle of 120, sp^2 hybridization - ANS-Trigonal planar

angle of 109, sp^3 - ANS-Tetrahedral

lewis structure --> hybridization --> geometry --> shape - ANS-Process to determine the shape

= the geometry of the molecule - ANS-Shape does not always

are counted as one center of e- density - ANS-Multiple bonds in VSEPR

Geometry - count all bonds and free pairs
Shape - count only bonds - ANS-Geometry vs shape

bent, angle = 120 - ANS-Trigonal planar with free pair, shape?

trigonal pyramidal - ANS-Tetrahedral with one free pair, shape?

bent - ANS-Tetrahedral with two free pairs, shape?
