No Marks. To determine what portion of the question you have correct, check question score at the top of the assignment. Draw the Lewis Structures for each of the following species to answer the questions.
Note: under "Exact?" indicate whether the angle you selected is exact or only approximate. When the central atom has one or more lone pairs, the angle is approximate.
The first atom in the formula is the central atom, so the C atom in COS would be the central atom.
In the last one, identify the structure around one carbon atom.
