How many unique structures are shown (i.e., how many structures with different molecular formulae)? Student Response Value Correct Answer Feedback 1. 4 2. 3 3. 5 4. 2 5. 1 100% General Feedback: All the same molecule. Some of the representations are awkward to draw and ugly, but they are correct. Score: 1/1 Comments: 2. Which of the following statements concerning the carbon dioxide molecule is correct? Student Response Value Correct Answer Feedback 1. The molecule contains four pi- bonds. 2. The molecule contains two lone pairs of valence electrons. 3. Each oxygen is described by sp 3 hybridization. 4. The carbon is described by sp 2 hybridization. 5. The molecule contains two sigma- bonds. 100% General Feedback: (a) Four lone pairs - two on each oxygen atom.(b) True - one sigma- & one pi-bond in each C=O bond.(c) Two - one in each double bond.(d) It is sp hybridized.(e) They are sp 2 hybridized.
