Thus, sp 3 hybridized atoms form longer and weaker bonds than those of sp 2 and sp hybridized. The greater the s-character, the closer the electrons are held to the nucleus, the shorter the bond, and the stronger the bond. Because of the tetrahedral molecular geometry, the calculate bond angles between 1 and 2, 1 and 3, 1 and 4, 2 and 3, 2 and 4, and 3 and 4. Hybridization and bond length/bond strength: The Bond Angle is 109.5 o: When the graphs of the four wave functions are combined, the resulting picture shows the tetrahedral arrangement of the four sp 3 hybrid orbitals around the central atom. Put differently, sp 3 species are less likely to get deprotonated (leaving a pair of electron behind). ![]() Therefore, when bearing the negative charge, sp 3 species are less stable than sp 2 and sp species. The closer the electrons are to the nucleus, the more stable they are. Since the s orbital is closer to the nucleus and thus lower in energy than the p orbital, the electrons of sp 3 hybridized species are held farther from the nucleus than those in sp 2 (33% s-character) and sp (50% s-character) hybridized species. In other words, it has 25% s-character and 75% p-character. S-character and the stability of the anion:Įach sp3 orbital has 1 part of s-character to 3 parts of p-character. Just like any other atomic orbital, each sp3 hybrid orbital can house 2 elections. The Energy level and election population:Īll four sp3 hybrid orbitals are delocalized-they occupy the same energy level however, they are higher in energy than the 2s orbital and lower in energy than the 2p orbital (figure 3). Because of the tetrahedral molecular geometry, the calculate bond angles between 1 and 2, 1 and 3, 1 and 4, 2 and 3, 2 and 4, and 3 and 4 approximately equal 109.5 o (figure 2). When the graphs of the four wave functions are combined, the resulting picture shows the tetrahedral arrangement of the four sp 3 hybrid orbitals around the central atom. ![]() Each hybrid orbital consists of a large lobe and a small lobe, pointing in two opposite direction (figure 1). Plotting any of these four wave functions gives a picture representation of a sp 3 orbital. Ψ(sp 3) = 0.5 ( ψ 2s + ψ 2px + ψ 2py + ψ 2pz) (1) Difference Between Sigma and Pi bond - Chemical Bonds - BYJU sigma ond and pi bond which is stronger mean SpletSigma and Pi Bonds Structure of Ionic Solids. In order for an atom to be sp 3 hybridized, it must have an s orbital and three p orbitals.įrom wave function to the visual representation:įour equivalent sp3 hybrid orbitals, resulting from the combination of one s atomic orbital and three p atomic orbitals, can then describe by four new wave functions (equations 1 – 4) The term “sp 3 hybridization” refers to the mixing character of one 2s-orbital and three 2p-orbitals to create four hybrid orbitals with similar characteristics.
