Which of the following species are incorrectly matched with their shape?

Options

A. `ClF_(3)=` trigonal planar
B. `SF_(4)=` folded square
C. `[XeF_(5)]^(-)=` pentagonal planar
D. `l_(2)Cl_(6)=` rectangular planar

Explanation

To determine which of the species are incorrectly matched with their shape, we will analyze each option one by one, drawing their structures and identifying their shapes.

### Step 1: Analyze ClF3
1. **Draw the Lewis Structure**: Chlorine (Cl) is the central atom with three fluorine (F) atoms bonded to it. There are also two lone pairs of electrons on the chlorine atom.
- Structure:
```
F
|
F-Cl
|
F
```
- Lone pairs are above and below the chlorine atom.

2. **Determine the Shape**: With three bonding pairs and two lone pairs, the molecular geometry is T-shaped (due to the repulsion of the lone pairs).

3. **Conclusion for ClF3**: The shape is T-shaped, but it is incorrectly matched as trigonal planar in the options.

### Step 2: Analyze SF4
1. **Draw the Lewis Structure**: Sulfur (S) is the central atom with four fluorine (F) atoms bonded to it and one lone pair of electrons on sulfur.
- Structure:
```
F
|
F-S
|
F
|
F
```
- The lone pair is positioned above the sulfur atom.

2. **Determine the Shape**: With four bonding pairs and one lone pair, the molecular geometry is a seesaw shape (also referred to as distorted tetrahedron).

3. **Conclusion for SF4**: The shape is correctly matched as distorted tetrahedron.

### Step 3: Analyze XeF5^-
1. **Draw the Lewis Structure**: Xenon (Xe) is the central atom with five fluorine (F) atoms bonded to it and one lone pair of electrons.
- Structure:
```
F
|
F-Xe-F
|
F
|
F
```
- The lone pair is positioned opposite to the fluorine atoms.

2. **Determine the Shape**: With five bonding pairs and one lone pair, the molecular geometry is square pyramidal.

3. **Conclusion for XeF5^-**: The shape is incorrectly matched as pentagonal planar.

### Step 4: Analyze I2Cl6
1. **Draw the Lewis Structure**: Iodine (I) is the central atom with six chlorine (Cl) atoms bonded to it. The structure exists in a dimer form.
- Structure:
```
Cl
|
Cl-I-Cl
|
Cl
|
Cl
|
Cl
```

2. **Determine the Shape**: The molecular geometry is rectangular planar.

3. **Conclusion for I2Cl6**: The shape is correctly matched as rectangular planar.

### Final Conclusion
- The incorrectly matched species with their shapes are:
- **Option A**: ClF3 is incorrectly matched as trigonal planar (correct shape is T-shaped).
- **Option C**: XeF5^- is incorrectly matched as pentagonal planar (correct shape is square pyramidal).

### Summary of Incorrect Matches:
- **ClF3**: Incorrectly matched as trigonal planar (correct shape: T-shaped).
- **XeF5^-**: Incorrectly matched as pentagonal planar (correct shape: square pyramidal).
