Transcript Ppt22b(PS10)_VSEPR outline

VSEPR plan
• Importance of molecular “shapes”
– Drug molecules / interactions
• CO2 vs SO2 vs H2O
– Similarities?
– Differences? (How to explain these?)
• Quick answer/run through
• 5 “Parent” Structures (What “family” are you in?)
• Importance of how to count electron “groups” (or
electron clouds) [not just for VSEPR!]
• My approach (Family first, then consider lone pairs)
