Among the following ,which one is the wrong statement

Options

A. `PH_(5)` and `BiCl_(5)` do not exist
B. `ppi-ppi` bonds are present in `SO_(2)`
C. `SeF_(4)` and `CH_(4)` have same shape
D. `I_(3)^(+)` has bent geometery

Answer

3

Explanation

`SeF_(4)implies` [steric number =`4`atoms+ `1` m lone pair]`implies`geometery is trigonal bipyramidal,shape is see -saw and `sp^(3) d` hybridization
`CH_(4)implies` [Steric number of `4` atoms+`0` lone pair]`implies`geometery as well as shape is trtrahedral an `sp^(3)` hybridization
(1) `H` is not sufficiently electronegative to contract `d`-orbitals and `Bi(+5)` is unstable due to incrt pair effect.
(2) In `SO_(2)` both `ppi-ppi` and `ppi-dpi` bonds are present
`I_(3)^(+) implies`[steric number=`2`atoms +`2` lone pairs ]`implies`geometery is tetrahedral shape is bent`//`angular and `sp^(3)` hybridization.
