Options

A. 0
B. 1
C. 2
D. 4

Explanation

To determine the number of dative (or coordinate) bonds in a sulfuric acid (H₂SO₄) molecule, we can follow these steps:

### Step 1: Understand the Structure of Sulfuric Acid
Sulfuric acid consists of one sulfur atom (S), four oxygen atoms (O), and two hydrogen atoms (H). The molecular structure can be represented as follows:
- The sulfur atom is at the center.
- Two of the oxygen atoms are bonded to sulfur with double bonds.
- The other two oxygen atoms are bonded to sulfur with single bonds, and each of these oxygen atoms is also bonded to a hydrogen atom.

### Step 2: Identify the Bonds in Sulfuric Acid
In sulfuric acid:
- The two double bonds between sulfur and the two oxygen atoms do not involve dative bonding.
- The two single bonds between sulfur and the other two oxygen atoms can involve dative bonding.

### Step 3: Determine the Dative Bonds
A dative bond (or coordinate bond) occurs when one atom provides both electrons for the bond. In sulfuric acid:
- Each of the two oxygen atoms that are singly bonded to sulfur can accept a hydrogen atom, which means that sulfur can donate a pair of electrons to form a bond with each of these oxygen atoms.

### Step 4: Count the Dative Bonds
Since there are two oxygen atoms that can form dative bonds with sulfur:
- There are **2 dative bonds** in sulfuric acid.

### Conclusion
The number of dative bonds in a sulfuric acid molecule is **2**.
