Draw the pu, d,2-,2 and d,2 orbitals on the x, y,z axes and identify the (+) and sign of the wave function. identify the point groups of these orbitals (with the signs in place). alternatively determine the symmetry elements of each of these species.

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.
