Discuss the structure of C2H4 depicting orbital overlap

Dear Student,

  • Molecular formula of ethene is C2H4.
  • In ethene, each carbon atom is sp2-hybridized. In this way six sp2-orbitals are generated (three for each carbon atom). One Sp2-orbital of each carbon atom by overlapping forms a sigma bond between carbon atoms. Remaining two sp2-orbital of each atom overlap with 1s-orbital of hydrogen atom to produce four sigma bonds. Pz un-hybrid orbital of each carbon atom by the parallel overlapping form a pi-bond between two carbon atoms.
  • Geometry ethene molecule is trigonal in which bond angles are120o.
  • The orbital overlap is shown in the figure :
