In an ideal Trigonal planar species, all three ligands are identical and the pairs are arranged along the central atom’s equator, with 120 o bond angles between them. Trigonal Planar Molecular Geometry. The degenerate hybrid orbitals formed from the standard atomic orbitals: sp hybridization occurs due to the mixing of one s and one p atomic orbital, sp2 hybridization is the mixing of one s and two p atomic orbitals and sp3 hybridization is the mixing of one s and three p atomic orbitals. Each sp hybridized orbital has an equal amount of s and p character, i.e., 50% s and p character. O bent - O linear O trigonal planar O trigonal bipyramidal O tetrahedral Hybridization is defined as the concept of mixing two atomic orbitals with the same energy levels to give a degenerated new type of orbitals. Even completely filled orbitals with slightly different energies can also participate.

The shape of the orbitals is planar triangular.Since there is an atom at the end of each orbital, the shape of the molecule is also planar triangular.molecule is also planar triangular. Summary Hybridization increases the overlap of bonding orbitals and explains the molecular geometries of many species whose geometry cannot be explained using a VSEPR approach. So its structure will be a trigonal planer structure. Atomic orbitals with equal energies undergo hybridization. Trigonal Pyramid. Since there are no unpaired electrons, it undergoes excitation by promoting one of its 2s electron into empty 2p orbital. The bigger lobe of the hybrid orbital always has a positive sign, while the smaller lobe on the opposite side has a negative sign. Still have questions? We can illustrate the comparison of orbitals and electron distribution in an isolated boron atom and in the bonded atom in BH 3 as shown in the orbital energy level diagram in Figure 8.
