Which of the following is not isostructural with SiCl4?

  • SCl4


  • SO42-
  • PO43- 

  • PO43- 


A.

SCl4

SCl4 is not isostructural of SiCl4 because it shows square planar structure due to the involvement of repulsion between lone pair and bond pair of electrons. 

SO42- shows tetrahedral structural due to sp3 hybridization
PO43- shows tetrahedral structural due to sp3 hybridization
NH4+ shows tetrahedral structural due to sp3 hybridisation
