The product of the reaction of phenol with bromine water is :

Options

A.
B.
C.
D. Both (1) and (3)

Answer

To determine the product of the reaction of phenol with bromine water, we can follow these steps:

### Step 1: Understand the Reactants
- **Phenol (C6H5OH)** is an aromatic compound with a hydroxyl (-OH) group attached to a benzene ring.
- **Bromine water** is a dilute solution of bromine (Br2) in water, which acts as a source of bromine in the reaction.

### Step 2: Reaction Mechanism
- When phenol reacts with bromine water, the bromine can undergo electrophilic aromatic substitution due to the activating effect of the hydroxyl group on the benzene ring.
- The hydroxyl group (-OH) is an electron-donating group, which increases the electron density on the benzene ring, making it more reactive towards electrophiles like bromine.

### Step 3: Identify the Product
- The bromination of phenol typically occurs at the ortho and para positions relative to the hydroxyl group.
- In the case of bromine water, the reaction leads to the formation of **2,4,6-tribromophenol** as the major product.
- This is because bromine can substitute at all three positions (2, 4, and 6) on the benzene ring due to the high reactivity of phenol in the presence of bromine.

### Step 4: Conclusion
- Therefore, the product of the reaction of phenol with bromine water is **2,4,6-tribromophenol**.

### Final Answer
The product of the reaction of phenol with bromine water is **2,4,6-tribromophenol**.
