Chapter 12, Problem 105TDI

Oxygen, ${\text{O}}_{\text{2}}$, dissolves quite well within a class of com-pounds known as liquid perfluorocarbons—so well that oxy-generated perfluorocarbons can be inhaled in a liquid phase. as is demonstrated by the rodent shown below the water bound goldfish. Do you suppose perfluorocarbon molecules are polar or nonpolar? Why would the rodent drown if it were brought up to the water layer, and why would the gold fish die if they swam down into the perfluorocarbon layer? How might perfluorocarbons be used to dean our lungs or serve as an artificial blood? When is it acceptable to sacri-fice the lives of animals for scientific research?
