`CO_(2)` is iso -structural with

Options

A. `SnCl_(2)`
B. `HgCl_(2)`
C. `SCl_(2)`
D. `ZnI_(2)`

Answer

B, D

Explanation

`CO_(2),HgCl_(2)` and `ZnI_(2)` are all linear wheras `SnCl_(2)` and `SCl_(2)` are bent.
Note: Use VSPER theory to predict the shape of molcules like `HgCl_(2),SnCl_(2),ZnI_(2),Scl_(2),CO_(2),NO_(2)` etc.
`O=C=O,Cl: Hg: Cl,H-C=C-H,I:Zn : I`
`Cl-underset(Cl)underset(|)(ddot(S)n), Cl-underset(Cl)underset(|)(ddot("S:")), ddot("O:")=underset(ddot("O:"))underset(|)(N)`
`NO_(2)` is an odd electron species with one 3e-2c bond.
