What is the product obtained in the Reimer-Tiemann reaction?

In which of the following reactions does carbon$-$carbon bond formation take place?

What amount of bromine will be required to convert $2 \ g$ of phenol into $2, 4, 6-$tribromophenol (in $g$)?

Assertion : Reimer-Tiemann reaction of phenol with $CCl_4$ in $NaOH$ at $340 \ K$ gives salicylic acid as the major product. Reason : The reaction occurs through intermediate formation of dichlorocarbene.

Phenol $+$ Aniline $\xrightarrow[{KOH}]{{C_6H_5N_2^+Cl^{-}}}$ Major Product $:$ Product will be $:$

Describe the reactions of nitration and bromination of phenol.
