Consider propane and ethylyne, The carbons in the latter molecule are sp hybridized, and the two p-orbitals that aren't being used that are aligned between the two carbons form two π bonds to form that triple bond. Carbon - carbon triple bond (sp hybridization) has more dissociation energy because it consists of three bonds (two pi bonds and one sigma bond) so it requires more energy to break the bonds than the other carbon- carbon double bonds (one pi bonds and one sigma bond) and carbon - carbon single bond (only one sigma bond). The more s character a bond has, the stronger it is, and so the higher. 5 o) z5 domains - trigonal bipyramidal (90 o & 120o). carbon-carbon triple bond; sp hybridization (linear) . Last Updated: February 15, 2022. When these sp 3 hybrid orbitals overlap with the s orbitals of the hydrogens in methane, you get four identical bonds.
