Bakelite is prepared by the reaction between

Options

A. urea and formaldehyde
B. ethylene glycol
C. phenol and formaldehyde
D. tetramethylene glycol

Explanation

To determine the correct answer to the question "Bakelite is prepared by the reaction between," we will analyze the options provided and explain the process of Bakelite formation step by step.

### Step 1: Identify the Components
Bakelite is a type of thermosetting plastic. The main components involved in its synthesis are phenol and formaldehyde.

### Step 2: Understand the Reaction
Bakelite is formed through a process called condensation polymerization. In this process, phenol (C6H5OH) reacts with formaldehyde (HCHO) to form a polymeric structure.

### Step 3: Write the Reaction
The reaction can be represented as follows:
1. **Initial Reaction**:
- Phenol (C6H5OH) + Formaldehyde (HCHO) → Hydroxybenzyl alcohol (C6H5CH2OH)

2. **Polymerization**:
- The hydroxybenzyl alcohol undergoes further reactions, losing water (H2O) and forming cross-linked structures, leading to the formation of Bakelite.

### Step 4: Conclusion
The overall reaction leads to the formation of Bakelite, which is a polymer made from phenol and formaldehyde. Therefore, the correct answer to the question is:

**Bakelite is prepared by the reaction between phenol and formaldehyde.**

### Final Answer:
**Phenol and formaldehyde.**
