Which of the following is not isostructural with SiCl4 ?
  1. A
    NH4−-−
  2. B
    SCl4
  3. C
    SO42−-−
  4. D
    PO43−-−

Correct answer: B

SiCl4, NH4+, SO42- and PO43- ions are the examples of molecules/ions which are of AB4 type and have tetrahedral structure. SCl4 is AB4(lone pair) types species. Although the arrangement of five sp3d hybrid orbitals in space is trigonal bipyramidal, due to the presense of one lone pair of electron in the basal hybrid orbital, the shape of AB4(lone pair) species gets distorted and becomes distorted tetrahedral or see-saw.
