41. Carbon tetrafluoride, CF4, and sulfur tetrafluoride, SF4, both have four fluorine atoms bonded to the central atom, but they have very different chemical and physical properties. Carbon tetrafluoride is a greenhouse gas, yet is relatively safe for human contact. On the other hand, sulfur tetrafluoride is extremely corrosive and releases toxic gas when exposed to moisture. a) Draw the Lewis structure of both molecules. CF4 SF4 b) What is the molecular shape of each molecule? CF4 SF c) Carbon tetrafluoride has a boiling point of -183C while sulfur tetrafluoride has a boiling point of -38C. Account for the difference in boiling points. d) As stated, sulfur tetrafluoride is soluble in water and releases a toxic gas. Draw a picture of what SF4 and water molecules would look like when mixed together. e) What is the toxic gas that is released when SF4 and water is mixed
