SO2Cl2


Correct answer explanation

Correct answer d. SO2Cl2

SO2Cl2 forms - bond, Sulphur has a d-orbital and oxygen has a p-orbital so it forms a bond with oxygen.

It forms a Sigma bond with chlorine. It has a tetrahedral shape with asymmetric distribution of charge on the Sulphur atom.

Structure

The explanation for the incorrect answer:

A. SiH4

Structure

Silicon has a tetrahedral shape as it forms a Sigma bond with hydrogen by the overlap of s and pz orbital.

Hence, option (A) is incorrect

B. CS2

Structure

CS2 forms a linear geometry by the overlap of p orbitals hence, option (B) is incorrect.

C. SO2

Structure

SO2 forms bond by interaction. Hence, option (C) is incorrect.

Hence, option (D) is the correct answer.
