SUMMARY
Ethylene (C2H4) is a planar molecule due to the requirement for effective orbital overlap in its pi bond. The molecular geometry is dictated by the sp2 hybridization of the carbon atoms, which leads to a trigonal planar arrangement. This configuration allows the p orbitals to align parallel, facilitating the formation of the pi bond. In contrast, higher analogues such as silane (Si2H6) and germane (Ge2H6) do not exhibit planarity due to differences in hybridization and steric factors.
