Draw the molecular geometry and indicate any deviations from ideal VSEPR coordination angles. Give the point group for each molecule.  \n(a) [10 pts] CH2Cl2 (b) [10 pts] XeO3  \nTd coordination, C2v trig pyramidal, C3v  \nOXeO \u003C 109.5°  \n(c) [7 pts] Is either of the above molecules chiral? Explain using symmetry rules.  \nNo, they both have mirror plane operations.  \n2. (a) [12 pts] Write down a Born-Haber analysis (give all the reaction steps) needed to estimate ∆Hf for CaO(s) from the elements in standard states. Label each reaction step with an appropriate energy term (such as I, Ea, ΔHL, etc) .  \nCa(s) → Ca (g)  \nCa(g) → Ca2+(g) + 2 e-½ O2 (g) → O(g)  \nO(g) + 2 e- → O2- (g) Ca2+(g) + O2- (g) → CaO (s)  \nΔHat(Ca)  \nI1(Ca) + I2(Ca)½ D0 (O-O)  \n- (Ea1(O) + Ea2(O))  \n- ΔHL (CaO)  \nCa(s) + ½ O2 (g) → CaO (s) ΔHf (CaO(s))  \nCorrect reactions steps [5]  \nCorrect label for energetics (I, Ea, ΔHL, etc) [4]  \nCorrect summation and signs [3]  \n(b) [7 pts] Is CaO(s) more or less soluble in polar solvents than KF (s)? Explain briefly.  \nMuch less soluble. CaO has a much larger lattice enthalpy due to the higher ion charges, this opposes ion solvation.  \n3. (a) [14 pts] Construct an MO diagram for the cyanide anion, CN¯(g), including valence atomic and molecular orbitals, symmetry labels, and the electron filling of the MO's.  \nCN¯ is isoelectronic and isolobal with CO. See the MO for CO  \nin text Fig. 2.22.  \n(b) [7 pts] Draw a figure showing the geometry of the LUMO orbital on CN¯ .  \n(c) [5 pts] Show with a simple picture how the LUMO in part (b) can act as a π– acceptor for transition metal cations.  \n4. A Latimer diagram for Cl at pH=0 is:  \nClO4¯ 1.20 V ClO3¯ 1. 18 HClO2 1.67 HClO 1.63 Cl2  1.36  Cl¯  \n(a) [10 pts] What is the standard potential for reduction of ClO3¯ to Cl¯ at pH=0 ?  \n[2(1.18) + 2(1.67) + 1(1.63) + 1(1.36)] / 6 = +1.45 V  \n(b) [10 pts] Does Cl2 disproportionate spontaneously in aqueous acid? Explain.  \nNo. The reaction Cl2 → Cl- + HClO has a negative potential (1.36 V – 1.63 V). Reactions to form chloride and HClO2 or Cl(V) or Cl(VII) also have a negative potential.  \n(c) [10 pts] Write a balanced half-reaction for the reduction of HClO to Cl2 in acidic solution.  \n2 e- + 2H+ + 2 HClO → Cl2 + 2 H2O  \n(d) [10 pts] Calculate the potential for the half-reaction in part (c) at pH = 3.  \nThe Nernst equation is E = E0 –(0 .059 V/ n) log Q  \nE = +1.63 – (3)(0.059) = +1.45 V  \n5. (a) [6 pts] Write out the full name of the octahedral complex [Mn(NH3)6]2+  \nhexamminemanganese(II) or hexaamminemanganese(2+)  \n(b) [10 pts] Write a d orbital energy level diagram for BOTH the strong-field (low spin) and weak-field (high spin) cases for the complex in part (a) . Label the dorbitals with (z2 , x2-y2 , xy, xz, and yz) and also give the orbitals symmetry labels.  \n(c) [10 pts] Calculate the ligand field stabilization energies (LFSE) in terms of ∆O for BOTH of the two electron configurations in part (a) .  \nHigh spin LFSE = zero; low spin is LFSE = 2.0 ΔO  \n(d) [8 pts] How would you experimentally determine the actual configuration (high or low-spin) for an Oh complex of Mn(II)?  \nMagnetic moment should be proportional to sqrt [N(N+2)]. [8 pts]  \nTrying to measure LFSE by calorimetry is not a good method. [4 pts if this]  \n6. (a) [10 pts] Write a balanced reaction showing how H2 is generated on an industrial scale.  \nCH4 (g) + H2O (g) → CO (g) + 3 H2 (g)  \nOr  \nC (s) + 2 H2O (g) → CO2 (g) + 2 H2 (g)  \nOr, electrolysis is OK  \n(b) [8 pts] Describe briefly 2 important ways that hydrogen bonding affects our daily lives.  \n1. Lower density of ice than water  \n2. DNA replication  \n3. High bp of liquid water.  \n7. [4 pts each] Circle the ONE best choice.  \n(a) Wurtzite structure has the stacking sequence of (AaBb)n, where uppercase letters are anions and lowercase are cations.
