Which of the following is not isostructural with S i C l 4 ?

Which of the following is not isostructural with SiCl4?
  1. SO42-
  2. PO43-
  3. NH4+
  4. SCl4

Solution

In SiCl4 there is sp3 hybridisation so the structure is tetrahedral. In SO42-, PO43-, NH4+ the structure is tetrahedral because in all hybridization is sp3. But in SCl4, sp3d hydridisation is present so shape is different which is see saw.
