Among the following which one is wrong-statement?

Options

A. `PH_5` and `BiCl_5` do not exist
B. `ppi-dpi` bonds are present in `SO_2`
C. `SeF_4` and `CH_4` have same shape
D. `I_3^(+)` has bent geometry

Answer

C

Explanation

`H_2` being a weak oxidising agent cannot oxidise P to its highest Q.S. of +5 and hence `PH_5` does not exist. Similarly, `Cl_2` being a weak oxidising agent cannot oxidise Bi to its highest O.S. of +5 and hence `BiCl_2` does not exist. `SO_2` has one `ppi-dpi` bond. In `SeF_4`, Se is `dsp^3`-hybridized and hence it has trigonal bipyramidal geometry while .C. in `CH_4` is `sp^3`-hiybridized and hence it has tetrahedral structure. `I_3^+` has bent structure.
