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 shape
D. `I_(3)^(+)` has bent geometry

Explanation

To determine which statement among the given options is incorrect, let's analyze each statement step by step:

1. **Statement 1: pH 5 and BCl5 do not exist.**
- **Analysis:** BCl5 (Boron Trichloride) is a well-known compound. However, it is important to note that BCl5 does not exist under normal conditions due to steric hindrance. This statement is correct.

2. **Statement 2: P pi d pi bonds are present in SO2.**
- **Analysis:** Sulfur dioxide (SO2) has a bent molecular geometry and involves double bonds between sulfur and oxygen. However, the bonding in SO2 primarily involves p orbitals rather than d orbitals. Therefore, this statement is incorrect.

3. **Statement 3: SF4 and CH4 have the same shape.**
- **Analysis:** CH4 (Methane) has a tetrahedral shape, while SF4 (Sulfur Tetrafluoride) has a seesaw shape due to the presence of lone pairs. This statement is incorrect.

4. **Statement 4: I3 has bent geometry.**
- **Analysis:** The I3- ion (triiodide) does indeed have a bent geometry due to the presence of lone pairs on the central iodine atom. This statement is correct.

**Conclusion:**
- The wrong statement among the given options is **Statement 2: P pi d pi bonds are present in SO2.**
