Diatomics, Lewis Structures, Formal Charges, MO Descriptions: The diatomics N2, CO, CNand NO+ are isoelectronic (have the same number of electrons). a) Give the Lewis structure for each and calculate the formal charges for each atom. N2 CN- CO NO+ b) Cyanide, CN-, can be oxidized to the neutral CN. Give the molecular orbital electronic configuration of CN- and CN and compute the bond order of each. Use the following horizontal form of the MO energy level diagram: [KK] σ2s σ*2s π 2p(x,y) σ2pz π*2p(x,y) σ*2pz c) Sketch the σ2pz and the π*2px molecular orbitals of CN- on the following coordinate systems. σ y π* 2pz x x C N y z y 2πx x x C N y d) The CN− anion has a C-N bond distance of 1.15 Å. Is the bond distance of neutral CN smaller or larger than 1.15 Å? Why? e) Which (CN- or CN) is paramagnetic and what is its spin-only magnetic moment? z CHEMISTRY 362-Worksheet 1.
