It is possible to get a false positive or false negative result when testing for ions. Suppose a situation that could lead to a false positive for a particular ion. Choose a different ion and show how a false negative could result. Which do you think is more likely to happen, a false positive or false negative result? Explain your reasoning.

Both 1,2−dihydronaphthalene and 1,4−dihydronaphthalene may be selectively hydrogenated to 1,2,3,4−tetrahydronaphthalene. one of these isomers has a heat of hydrogenation of 101 kj/mol (24.1 kcal/mol), and the heat of hydrogenation of the other is 113 kj/mol (27.1 kcal/mol). match the heat of hydrogenation with the appropriate dihydronaphthalene.
