1. Describe the shape of each of the following molecules. You will need to draw the Lewis structures. N 2 O (N is central) bent with ~109 o bond angles linear bent with ~120 o bond angles HCN (C is central) bent with ~109 o bond angles linear bent with ~120 o bond angles OF 2 (O is central) linear bent with ~120 o bond angles bent with ~109 o bond angles Which of these molecules have resonance structures? (Check all that are correct.) HCN OF 2 N 2 O none of the molecules have resonance structures 2. You will need to draw the Lewis structure of SCl 2 in the process of answering this question. a) How many shared pairs are in this molecule? 2 b) How many lone pairs are on the sulfur atom? 2 c) What is the S/Cl bond order? 1 3. You will need to draw the Lewis structure of PF 3 in the process of answering this question.

Unformatted text preview: a) How many shared pairs are in this molecule? 3 b) How many lone pairs are on the phosphorus atom? 1 c) What is the P/F bond order? 1 4. You will need to draw the Lewis structure of O 3 in the process of answering this question. Note that O 3 has one oxygen central, flanked by the other two (the two end oxygen atoms are not bonded to each other). a) How many shared pairs are in this molecule? 3 b) How many total lone pairs are in the molecule? 6 c) What is the O/O bond order? 1.5 5. For each answer in this question, type a number , not a word. Note that you drew the Lewis structures for these molecules in the previous questions. What is the formal charge on: a) S in SCl 2 0 b) P in PF 3 0 c) the central O in O 3 +1...
