Nascent hydrogen consists of

Options

A. hydrogen atoms with excess energy
B. hydrogen molecules with excess energy
C. hydrogen ions in the excited state
D. solvated protons.

Explanation

To solve the question "Nascent hydrogen consists of," we can break down the information provided in the video transcript step by step.

### Step-by-Step Solution:

1. **Understanding Nascent Hydrogen**:
- Nascent hydrogen refers to hydrogen that is in a very reactive state, often produced during chemical reactions. It is not in its stable molecular form (H₂).

2. **Identifying the Options**:
- The options given are:
1. Hydrolyzed hydrogen atom with excess energy
2. Hydrogen molecule with excess energy
3. Hydrogen ions in the excited state
4. Solvated proton

3. **Analyzing Each Option**:
- **Option 1**: Hydrolyzed hydrogen atom with excess energy - This does not accurately describe nascent hydrogen.
- **Option 2**: Hydrogen molecule with excess energy - This option suggests that when a hydrogen molecule (H₂) is provided with excess energy, it can break apart to form nascent hydrogen, which is correct.
- **Option 3**: Hydrogen ions in the excited state - While hydrogen ions can be reactive, this does not specifically define nascent hydrogen.
- **Option 4**: Solvated proton - This refers to protons surrounded by solvent molecules, which is not the same as nascent hydrogen.

4. **Conclusion**:
- Based on the analysis, the correct answer is **Option 2: Hydrogen molecule with excess energy**. This is because nascent hydrogen is formed when H₂ molecules are energized and dissociate into individual hydrogen atoms that are highly reactive.

### Final Answer:
Nascent hydrogen consists of hydrogen molecules with excess energy.
