Is ethene tetrahedral sp3 or planar?

1 Answer

Trigonal Planar


The overall structure of the ethene compound is linear but the molecular geometry around each carbon atom is trigonal planar.

It is #"sp"^2# hybridization. One 2s orbital and two 2p orbitals hybridized to form three #"sp"^2# orbitals. To find the hybridization of an atom, just count the number of atoms bonded to it and the number of lone pairs.
