Among the following orbital bonds, the angle is minimum between

Options

A. `sp^3` bond
B. `p_x and p_y` -orbitals
C. H-O-H in water
D. sp bonds

Explanation

To determine which of the given orbital bonds has the minimum angle between them, we will analyze each case step by step.

### Step 1: Analyze sp³ Hybridization
- **Hybridization Type**: sp³
- **Geometry**: Tetrahedral
- **Bond Angle**: The bond angle in sp³ hybridization is approximately 109.5 degrees.

### Step 2: Analyze px and py Orbitals
- **Orbital Type**: px and py
- **Orientation**: The px orbital is aligned along the x-axis, and the py orbital is aligned along the y-axis.
- **Bond Angle**: The angle between the px and py orbitals is 90 degrees, as they are perpendicular to each other.

### Step 3: Analyze H₂O Molecule
- **Molecule**: Water (H₂O)
- **Geometry**: The shape is V-shaped due to the presence of two lone pairs on the oxygen atom.
- **Bond Angle**: The ideal tetrahedral angle is 109.5 degrees, but due to lone pair repulsion, the bond angle in H₂O is reduced to approximately 104.5 degrees.

### Step 4: Analyze sp Hybridization
- **Hybridization Type**: sp
- **Geometry**: Linear
- **Bond Angle**: The bond angle in sp hybridization is 180 degrees.

### Conclusion
Now that we have analyzed all the cases:
- sp³: 109.5 degrees
- px and py: 90 degrees
- H₂O: 104.5 degrees
- sp: 180 degrees

The minimum bond angle is found between the px and py orbitals, which is **90 degrees**.

### Final Answer
The angle is minimum between **px and py orbitals** (Option B).
