Question

What is the hybridization of the carbon atom in the molecule C2H2?

Answer 1

The hybridization of the carbon atom in the molecule C2H2  acetylene  is sp. Each carbon atom in C2H2 forms two sigma bonds  one with another carbon atom and one with a hydrogen atom  and two pi bonds  with the other carbon atom . The formation of two sigma bonds requires two hybrid orbitals, which are formed by the combination of one s orbital and one p orbital, resulting in sp hybridization.
