Chapter 5, Problem 32E

Chlorofluorocarbons have been banned because they cause ozone depletion. The main replacements are hydrofluorocarbons, such as ${\text{CF}}_{\text{3}}{\text{CFH}}_{\text{2}}\text{.}$ Draw a Lewis structure for ${\text{CF}}_{\text{3}}{\text{CFH}}_{\text{2}}\text{,}$ determine its geometry, make a sketch of the molecule, and determine whether it is polar. (The two carbons are bonded to each other in the middle of the molecule, and the other atoms are bound to the two central carbon atoms.)
