Name Ch 1a, Problem Set Six Section Side 1 of 1 Due Friday, Nov. 5, 2004 Rec TA at 4 PM in the SAC Problems one and four are designated ( ) as “no collaboration” problems. Recall that from now on, problem sets are worth 200 points, and you may not substitute your Quiz One score for these sets. 1. (60 Points, 10 Each) For each of the following molecules, draw a Lewis dot structure and state its geometry using VSEPR. Show any significant resonance structures and formal charges. a. CO 2 b. PF 5 c. CO d. PH 3 e. HCP f. IF 3 2. (40 Points, 8 Each) For each of the following molecules, draw a Lewis dot structure and then state its geometry using VSEPR. Show any significant resonance structures and formal charges. a. BrF 5 b. N 2 O c. CH 3 CCH d. H 2 NBH 2 e. SF 2 O 3. (40 Points, 10 each) When drawing Lewis dot structures, many students encounter the pitfall of thinking in only two dimensions, even though molecules exist in three dimensions. Several phosphorus compounds show interesting architectures for which
