The compound containing coordinate bond is

Options

A. `O_(3)`
B. `SO_(3)`
C. `H_(2)SO_(4)`
D. All of these

Explanation

To determine which compound contains a coordinate bond, we need to analyze the structures of the given compounds. Here’s a step-by-step solution:

### Step 1: Understand Coordinate Bonds
A coordinate bond (or dative bond) is formed when one atom provides both electrons for a shared pair in a covalent bond. Typically, this occurs when a Lewis base (which has a lone pair of electrons) donates that pair to a Lewis acid (which has an empty orbital).

### Step 2: Analyze Ozone (O3)
- Ozone consists of three oxygen atoms.
- In its structure, one oxygen atom forms a double bond with another oxygen atom and has a lone pair that can be donated to the third oxygen atom.
- This results in a coordinate bond between the oxygen with the lone pair and the other oxygen atom.

### Step 3: Analyze Sulfur Trioxide (SO3)
- Sulfur trioxide has a sulfur atom bonded to three oxygen atoms.
- In this case, one of the oxygen atoms can donate a lone pair to the sulfur atom, forming a coordinate bond.
- Therefore, SO3 contains coordinate bonds as well.

### Step 4: Analyze Sulfuric Acid (H2SO4)
- In sulfuric acid, the sulfur atom is bonded to four oxygen atoms, two of which are connected through hydroxyl (OH) groups.
- The sulfur can utilize its lone pairs to form coordinate bonds with the oxygen atoms.
- Thus, H2SO4 also contains coordinate bonds.

### Step 5: Conclusion
After analyzing the structures:
- Ozone (O3) has one coordinate bond.
- Sulfur trioxide (SO3) has two coordinate bonds.
- Sulfuric acid (H2SO4) has two coordinate bonds.

### Final Answer
All three compounds (O3, SO3, and H2SO4) contain coordinate bonds. Therefore, the correct answer is that the compound containing coordinate bonds is **D) All of the above**.
