1. Determine whether each statement below is True (T) or False(F). a. ____ If A,B and C are elements whose electronegativitiessatisfy xA > xB > xC, then then (ΔAC)1/2 = (ΔAB)1/2 +(ΔBC)1/2 if the Pauling electronegativity scale is valid. b. ____There is no interelectronic repulsion in the H2+ molecule. c. ____The wave function N(1sA + 1sB) is the exact electronic wavefunction for the ground electronic state of H2+. d. ____ The planeperpendicular to the molecular axis at the midpoint between thenuclei in H2+ is a node for the first excited state. e. ____ Themolecular electron probability density is experimentallyobservable. f. ____ The molecular wave function is experimentallyobservable. g. ____ The bonding MOs of BeH2 extend over all threeatoms and the hybridization of AOs are approximately sp2. h. ____ ASCF wave function is one in which each electron is assigned to asingle spin-orbital, the spatial part of each spin-orbital isexpressed as a non- linear combination of basis functions, and thecoefficients in these combinations are found by solving theHartree-Fock equations. i. ____The molecular-mechanics method is anempirical quantum mechanical method that treats the molecule asatoms held together by bonds and writes the molecular steric energyas the sum of contributions from bond bending and stretching, bondtorsion and van der Waals and electrostatic interactions ofnon-bonded atoms. j. ____ The molecular-mechanics method can beapplied to very large molecules and yields good results whenapplied to molecules similar to those for which the force field wasparametrized. k. ____ The maximum electron probability density inthe ground electronic state of H2+ occurs at each nucleus. l. ____If sufficient basis functions are used, the Hartree-Fock wavefunction of a many-electron molecule will reach the true wavefunction. m. ____ In a homonuclear diatomic molecule, combining two2p AOs always yields a π MO. n. ____ In homonuclear diatomicmolecules, all u MOs are antibonding. o. ____ A decrease inviscosity with increasing rate of flow of a solution indicates thepresence of long rod-like molecules that are orientated by theflow.
