In the Reimer-Tiemann reaction where Phenol reacts with ${\text{CHCl}}_3$ and $\text{NaOH}$, the electrophile involved is:

Carboxylic acids have higher boiling points than aldehydes, ketones and even alcohols of comparable molecular mass. It is due to their:

Compound $A,{\text{C}}_8{\text{H}}_{10}\text{O}$, is found to react with $\text{NaOI}$ (produced by reacting $Y$ with $\text{NaOH}$) and yields a yellow precipitate with characteristic smell. $A$ and $Y$ are respectively:
