  1. CHP 16 • A2 N AB3, sp2: NO2–, NO3–, FNO (AB2E), NO (ABE2), very close to sp, Why ? Lone pair and single e around N atom, strong repulsion N AE2, sp: The others.

  2. A4: Polarization and Reducity • (NH4)(NO3) N2O + H2O • Cu(NO3)2. nH2O CO + NO2 + O2 + H2O • Cu(NO3)2 + H2O • Cu(NO2)2 + O2 + H2O • CuO + N2O3 • NO + NO2 • NO2

  3. A8 • H+ + HNO2 + Fe2+ Fe(NO)3+ + H2O H2O + NO+

  4. B3 • First: radius F ~ N < Cl Overlap: F–N Good; Cl–N Poor Bond Energy: F–N > Cl–N repulsion of group: F < Cl • Electronegativity: F > N > Cl (Cl positive) Repulsion of bonding e around N Atom: F < Cl Energy of anti bonding energy: F > Cl Energy of lone pair e energy: F < Cl • Cl has empty d orbitals
