How many bonds can an atom form using sp3 hybrid orbitals?


How many bonds can an atom form using sp3d hybrid orbitals?


In the valence bond theory description of methane, which of the following statements is not a valid justification for the use of sp3 hybrid orbitals?

  • AThe C H bonds are exactly equivalent so must be generated by orbitals of equal energy.
  • BThe s orbital of each H atom must overlap with the s orbital of the C atom and at least one p orbital.
  • COverlap of the H s orbitals with the three p orbitals of the C atom would produce bonds at 9 0 to each other.
  • DA C atom could not form four bonds without hybridization, as the energy for promoting a 2s electron to the 2p subshell is too large.
  • EA tetrahedral bonding geometry with zero dipole moment is only possible if electron density is distributed equally between the four bonds.
