Identify the molecular structure of ethene (C2H4). Ethene consists of two carbon atoms double-bonded to each other, with each carbon atom also bonded to two hydrogen atoms.
Understand the concept of hybridization: Hybridization is the mixing of atomic orbitals to form new hybrid orbitals that can form sigma bonds or accommodate lone pairs.
Determine the type of bonds present in ethene: Each carbon atom forms three sigma bonds (two with hydrogen atoms and one with the other carbon atom) and one pi bond (the second bond in the double bond between the carbon atoms).
Recognize the hybridization state: For a carbon atom forming three sigma bonds, the hybridization is sp2. This involves the mixing of one s orbital and two p orbitals to form three sp2 hybrid orbitals.
Conclude that in ethene, each carbon atom is sp2 hybridized, allowing for the formation of a planar structure with 120-degree bond angles, which is characteristic of sp2 hybridization.
