Document Summary
Draw the contour diagram for the end-on interaction between two (cid:1856)(cid:1006)orbitals and two (cid:1842) orbitals that results in and mos. Heteronuclear diatomics can have sp mixing or not. Whether a heteronuclear diatomic compound has sp mixing is not predictable it must be experimentally determined. For example, no (mo diagram to the side) does not have sp-mixing, but co does. The first ionization energy of no is 891 kj/mol, that of n2 is 1500 kj/mol, and that of co is 1350 kj/mol. Use mo electron configurations to explain why no ionizes more easily than either n2 or. The hybridization model gives similar information for the s bonding of various. No valence (cid:1857) is in whereas (cid:1840)(cid:1006)and co are in. For compounds larger than diatomics, the bonds can be described with mo theory, but using mo theory to describe the bonds is a little more complicated and often.
