Detailed Solution

In the Reimer - Tiemann reaction, phenol reacts with chloroform in the presence of sodium hydroxide. This reaction results in the formation of Salicylaldehyde.

In Kolbe's reaction, phenol is treated with NaOH, which results in the formation of Phenoxide ion. Then, it undergoes electrophilic substitution with carbon dioxide, a weak electrophile. Ortho hydroxybenzoic acid is formed as the main reaction product.
