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

Options

  1. AS O 4 2 -
  2. BP O 4 3 -
  3. CN H 4 +
  4. DS C l 4

Correct answer

D. S C l 4

Step-by-step solution

In S i C l 4 there is s p 3 hybridisation so the structure is tetrahedral. In S O 4 2 - , P O 4 3 - , N H 4 + the structure is tetrahedral because in all hybridization is s p 3 . But in S C l 4 , s p 3 d hydridisation is present so shape is different which is see saw.
