Apart from tetrahedral geometry, another possible geometry for CH4is square planar with the four H atoms at the corners of the square and the C atom at its centre.Why CH4does not have square planar geometry?
ChemistryChemical Bonding and Molecular StructureNEET
Options:
  • A CH4is not square planar because carbon cannot form square planar geometry due to its atomic structure.
  • B CH4is not square planar because square planar geometry requires the presence of two lone pairs of electrons on the central atom, and carbon in CH4does not have any lone pairs.
  • C CH4is not square planar because square planar geometry would result in high repulsion between the four hydrogen atoms.
  • D CH4is not square planar because square planar geometry is not energetically favorable for the molecule.

The correct answer is: CH4is not square planar because square planar geometry requires the presence of two lone pairs of electrons on the central atom, and carbon in CH4does not have any lone pairs.
Correct Option is : (B)
CH4is not square planar because square planar geometry requires the presence of two lone pairs of electrons on the central atom, and carbon in CH4does not have any lone pairs.
