In the hybrid orbital picture of acetylene, both carbons are sp-hybridized. Similarly, for a triple bond formation, like for that of acetylene molecule, there is sp hybridization between 1 s and 1 p orbital of the carbon atom. The electrons rearrange themselves again in a process called hybridization. These orbital are coplanar and directed towards the corners of an equilateral triangle at an angle of 120 o from each other. Each carbon atom in excited state undergoes sp hybridization giving rise to two hybrid orbitals each. 0 votes . • 1 Answer. The two hybrid orbitals of each carbon atom are used up in forming C-C and C-H sigma bonds. Therefore both carbon atoms produce sp hybridization and leaving two p orbitals pure ( un hybridized).
