Answer :
To determine which molecule has a bent shape, let's analyze the provided options:
1. A. BeCl₂:
- Beryllium Chloride (BeCl₂) falls under the category of molecules with the chemical formula AX₂.
- Beryllium Chloride in its ground state adopts a linear shape due to sp hybridization, resulting in a bond angle of 180°.
- Hence, BeCl₂ has a linear shape, not a bent shape.
2. A. 69:
- The entry "69" is not a chemical molecule, so it is irrelevant to the question of molecular shapes.
- Therefore, this option can be disregarded.
3. C. NH₃:
- Ammonia (NH₃) has a chemical formula of AX₃E, where E represents a lone pair on the central nitrogen atom.
- The shape NH₃ adopts is known as "trigonal pyramidal" due to the lone pair-bond pair repulsion lowering the bond angle to approximately 107°.
- As a result, NH₃ has a trigonal pyramidal shape, not a bent shape.
4. D. 130:
- Similar to "69," the entry "130" is not relevant to molecular shapes because it does not represent a chemical molecule.
- Thus, this option can also be disregarded.
Conclusively, among the options provided (A, 69, NH₃, 130), none of the molecules or entries exhibits a bent shape. Therefore, the correct answer is:
```
None
```
