In urotropine, the number of N-N bond

Options

A. 6
B. 4
C. 2
D. 0

Explanation

To determine the number of N-N bonds in urotropine, we will follow these steps:

### Step 1: Understand the Structure of Urotropine
Urotropine, also known as hexamethylenetetramine (HMTA), is formed from the reaction of formaldehyde with ammonia. Its structure consists of a central carbon atom bonded to nitrogen atoms and methylene (-CH2-) groups.

### Step 2: Draw the Structure
The structure of urotropine can be visualized as follows:
- It has a cage-like structure where four nitrogen atoms are connected through methylene (-CH2-) groups.
- Each nitrogen atom is bonded to two methylene groups.

### Step 3: Identify N-N Bonds
In the structure:
- The nitrogen atoms are connected to each other through methylene groups, not directly.
- Therefore, there are no direct N-N bonds present in the structure.

### Step 4: Conclusion
Since all the nitrogen atoms are connected via methylene groups, the number of N-N bonds in urotropine is **0**.

### Final Answer
The number of N-N bonds in urotropine is **0**.
