Convert phenol into
(i) Salicylaldehyde (ii) Benzene
(iii) Picric acid (iv) Benzoic acid
(v) Aspirin (vi) Salicylic acid

Explanation

To convert phenol into the specified compounds, we can follow these steps:

### (i) Conversion of Phenol to Salicylaldehyde
1. **Start with Phenol (C6H5OH)**.
2. **Perform the Demerger reaction**: React phenol with chloroform (CHCl3) in the presence of sodium hydroxide (NaOH).
3. **Acidify the reaction mixture**: After the reaction, add HCl to the mixture to convert the intermediate into salicylaldehyde (C6H4(OH)CHO).

**Reaction**:
