Carbon orbital diagram

With the next element, carbon, a complication arises. In which orbital should the sixth electron go It could go in the same orbital as the other 2p electron, in which case it would have to have the opposite spin, [. It could go into one of the other two orbitals, either with a parallel spin, f, or an opposed spin, Experiment shows that there is an energy difference among these arrangements. The most stable is the one in which the two electrons are in different orbitals with parallel spins. The orbital diagram of the carbon atom is... 

Figure 6-12. Schematic molecular orbital diagram for carbon monoxide.

Caulton and Fenske began with a molecular orbital diagram for CO (see Fig. 1). The two orbitals of interest here are, of course, the Scr- and 277-orbitals. The Sa-orbital, assumed in valence-bond theory to be a carbon orbital, has in reality a small contribution from oxygen also (Sa = 0.664 2s + 0.059 2s — 0.664 2p — 0.364 2p ). One can see from the choice of... 

The central carbon is surrounded by three electron groups and is sp2 hybridized. The orbital diagrams for the un-hybridized atoms are ... 

Lets look at the ground state electron configuration and orbital diagram of carbon (6C) which is the first element in group 4A. 

Considering the molecular orbital diagram of carbon monoxide (Fig. 5.201 and the discussion concerning hybridization and energy (pages 225-227). predict which end of the carbon monoxide molecule will be the more basic (i.e., will donate electrons more readily and form the stronger, direct covalent bond)... 

Returning to the transition metal monocarbides, Figure 5.6 now provides a more familiar correlation diagram showing the hybridization between metal orbitals and carbon orbitals to produce the monocarbides with the NaCl structure. The p-orbitals are shown as being composed of the pxpy and pz orbitals where the, y, and z axes are now relative to some arbitrary plane in which the x and y axes are parallel to this plane and the z axis is its normal. Relative to the same plane, the d-orbitals are split into... 

The orbital diagram for. (//-hybridized nitrogen is the same as for. (//-hybridized carbon, except nitrogen has one more electron. 

Match the orbital diagram for the ground state of carbon with the rule/principle it violates ... 

Orbital diagram of the methyl cation. The methyl cation is similar to BH3. The carbon atom is a bonded to three hydrogen atoms by overlap of its sp2 hybrid orbitals with the s orbitals of hydrogen. A vacant p orbital lies perpendicular to the plane of the three C —H bonds. 

The orbital diagram—the kind you met in Chapter 4—represents the C-Li bond in methyl-lithium in terms of a sum of the atomic orbitals of carbon and lithium. Remember that, the more... 

Before leaving the carbonates, we should note that carbon in four coordination with oxygen is observed in inorganic compounds and has been studied quantum mechanically. Tossell (1976b) calculated a molecular-orbital diagram for for a range of distances the results showed... 

The configuration for carbon could be written ls22s12p12p1 to indicate that the electrons occupy separate 2p orbitals. However, the configuration is usually given as ls22s22p2, and it is understood that the electrons are in different 2p orbitals. The orbital diagram for carbon is... 

Figure 3. Molecular orbital diagram of a tetrahedral carbon compound (schematic)...

The m.o. diagram for CO2 is thus as shown in Fig. 9.2, considering that] the bonding orbitals have lower energy than the tt ones and that ai is thej lowest in energy, as the energy associated with the 2s carbon orbital is lower than 2p.
