Among the following which one is wrong-statement?

Options

A. `PH_5 and BiCl_5` do not exist
B. ` p pi - d pi` bonds are present in `SO_2`
C. `SeF_4` and ` CH_4` have same shope
D. `I_(3)^(+)` has bent geometry

Answer

C

Explanation

`H_2 ` being a weak oxidising agent cannot oxidise P to its highest O.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 ` p pi - d pi` bond
In `SeF_4, Se` is `dsp^3` -hybridized and hence it has trigonal bipyramidal geometry while .C. in `CH_4` is sphybridized and hence it has tetrahedral structure. `I_(3)^(+)` has bent structure.
