The major product of the following reaction is:

What amount of bromine will be required to convert $2 \ g$ of phenol into $2, 4, 6-$tribromophenol (in $g$)? $($Given molar mass in $g \ mol^{-1}$ of $C, H, O, Br$ are $12, 1, 16, 80$ respectively$)$

What happens when $phenol$ reacts with bromine water?

Carbolic acid is oxidised by acidified sodium dichromate to give

Which of the following reactions will form a tri-bromo derivative of phenol?
