CHEM 130 Lecture 14: chem lect 14
Document Summary
Clicker: what is the molecular geometry of icl4: octahedral, seesaw, square planar, square pyramidal, tetrahedral. Clicker: what is the molecular geometry of icl3: bent, triganol bipyramidal, triganol planner, trigonal pyramidal, t-shaped. Lone pairs:take up more space than bonding pairs so they compress the angles btwn bonding pairs. Multiple bonds in the vsepr model: double bonds and triple bonds count as one center of electrons density: counts as one electron pair. Multiple bonds and bond angles: multiple bonds require more space than single bonds, so they compress the other bond angles. Resonance structures: you can choose any resonance structure to determine electrons pair arrangement and molecular geometry: often you will have multiple resonance structures, you can use any to gure out molecular geometry. What is the bond angle: bent (~109. 5, bent (~120, linear, triganol planar, t-shped. Clicker: which o the following would you expect to best approximate the h-c-h bond angle inn.
