By John G. Verkade

Knowing molecular orbitals (MOs) is a prerequisite to appreciating many actual and chemical houses of subject. This commonly revised moment version of A Pictorial method of Molecular Bonding offers the author's leading edge method of MOs, producing them pictorially for a wide selection of molecular geometries. a massive enhancement to the second one variation is the computer- and Macintosh-compatible Nodegame software program, that is coordinated with the textual content and aids in pictorially instructing molecular orbital thought utilizing generator orbitals.

These hybrid AOs can also be written in more general form as in Equation 2-44: (2-44) wherein the (2pfk) orbitals are defined in the case at hand by Equation 2-45: (2pfd = (2px) 1 (2pf2) = -2(2px) 1 + 2j3(2PY) (2-45) 1 1 (2pf 3) = -2(2px) - 2j3(2py). The (2pfk) orbitals point in the directions fl = (1,0,0), f2 = (-1/2,3 1/ 2 /2,0), f 3 = ( - 1/2, - 3 1 / 2 /2, 0). These vectors are of unit length so that the (2pfk) are normalized. As shown in Figure 2-17a, the unit vector directions are at 120° to one another as are the (Sp2) hybrids which point along these directions.

2-18) Since the three orbitals in Equations 2-17 are each a function of a single coordinate, Equation 2-18 can be recast into Equations 2-19 which are algebraic expressions for the projections of r onto the three coordinate axes: 35 Hybrid Orbitals I I I\ I I (x, y, z) - - - .............. ):::::=::t>--- y I! / I (~= -------~~ x 0, 1) I :\ ~==~--~*-~y e ~---+-~y ,II I ................................................. :L_V x x (a) (b) (c) Figure 2-10.

A unit vector e is one unit long as measured in whatever units we are working with. In Figure 2-10b the unit vector has been placed along the y axis. Then the projection of r onto e denoted by Peer) and shown in Figure 2-lOc is given by the so-called "dot product" (e' r) which is defined in Equation 2-18: Peer) = (e' r) = ~x + 11Y + (z.
