What is formed when chloroform reacts with heavy water?

Answer

To determine what is formed when chloroform reacts with heavy water, we can follow these steps:

### Step 1: Identify the Reactants
The reactants in this reaction are:
- Chloroform (CHCl₃)
- Heavy water (D₂O), which is deuterium oxide

### Step 2: Understand the Nature of the Reaction
This reaction is classified as an exchange reaction. In this type of reaction, the active hydrogen atoms in chloroform are exchanged with deuterium atoms from heavy water.

### Step 3: Write the Reaction Equation
The reaction can be represented as follows:
\[ \text{CHCl}_3 + \text{D}_2\text{O} \rightleftharpoons \text{CDCl}_3 + \text{HOD} \]

### Step 4: Identify the Products
From the reaction, we can see that the products formed are:
- Deuterochloroform (CDCl₃)
- Hydroxide deuterium (HOD)

### Step 5: Conclusion
When chloroform reacts with heavy water, the products formed are deuterochloroform (CDCl₃) and hydroxide deuterium (HOD).

### Final Answer
The products formed when chloroform reacts with heavy water are:
- Deuterochloroform (CDCl₃)
- Hydroxide deuterium (HOD)
