Explanation

### Step-by-Step Solution

#### (a) Reactions Involved

**(i) Reimer-Tiemann Reaction:**
The Reimer-Tiemann reaction involves the reaction of phenol with chloroform (CHCl3) in the presence of a strong base, typically potassium hydroxide (KOH). The reaction leads to the ortho-formylation of phenol, producing ortho-hydroxybenzaldehyde (salicylaldehyde).

**Reaction:**
