Intermixing of one 's' and one 'p' orbitals of almost equal energy to give two identical and degenerate hybrid orbitals is called 'sp' hybridization. Hybridisation In the case of ethene, there is a difference from, say, methane or ethane, because each carbon is only joining to three other atoms rather than four. Again, numbering is irrelivant. 19 2 2 bronze badges $\endgroup$ $\begingroup$ "Stability" is another word for "energy difference between one state and another". When the carbon atoms hybridise their outer orbitals before forming bonds, this time they only hybridise three of the orbitals rather than all four. Each carbon is only joining to two other atoms rather than four (as in methane or ethane) or three (as in ethene). 2. In C2H6, 1 s orbital and three p-orbitals (px, py, pz) take part in hybridization. In nature, it is released in trace amounts by plants to signal their fruits to ripen.

The equation for the hydrogenation of ethyne is C2H2 + 2H2 --> C2H6. Similar consider- ations were applied to explain the influence of carbon monoxide, which is known to increase the overall selec- tivity: like ethyne, CO adsorbs stronger than ethene and thus in the presence of CO the surface coverage of ethene remains low, even at low ethyne pressures. Thus, the geometry around one carbon atom is planar, and there are un-hybridized p orbitals in carbon atoms. In ethene, the number of sigma bonds are 3 hence the hybridisation is sp2. Interesting note: Rotation about triple bonds is actually okay; Overlap between p orbitals is continuous enough through rotation. Rank these compounds by the length of the carbon-carbon bond.
