10 sie 2021 · In a C-C triple bond, each of the carbon atoms is sp-hybridized, making the geometry of alkynes linear. Two sp-hybridized orbitals make \(σ\) bonds, while the two orthogonal atomic p orbitals make two \(π\) bonds that are also orthogonal to one another.
Structure and Hybridization of Alkynes. The carbon atoms in the triple bond are sp-hybridized. Remember, in the sp hybridization, the s orbital of the excited state carbon is mixed with only one out of the three 2p orbitals. It is called sp hybridization because two orbitals (one s and one p) are mixed:
In the language of valence bond theory, the carbon atoms in an alkyne bond are sp hybridized: they each have two unhybridized p orbitals and two sp hybrid orbitals. Overlap of an sp orbital from each atom forms one sp–sp sigma bond. Each p orbital on one atom overlaps one on the other atom, forming two pi bonds, giving a total of three bonds.
Hydroboration-Oxidation of Alkynes: Hydroboration-oxidation also applies to alkyne in a similar way as to alkene. The two-step process results in the enol, which goes through tautomerization to give a carbonyl compound.
