Phenol is heated with a solution of a mixture of $KBr$ and $KBrO_3$. The major product obtained in the above reaction is:

Identify $(C)$ in the reaction$(s)$:
$p\text{-toluidine}$ $\xrightarrow[{0\,^{\circ}C}]{{NaNO_2/HCl}}\,(A)\,$ $\xrightarrow{{{H_2}O, \Delta }}\,(B)\,$ $\xrightarrow[{(ii)\,dil.\,HCl}]{{(i)\,CHCl_3, KOH, \Delta }}\,(C)$

Assertion: Phenyl is used as a household germicide.
Reason: Phenyl is a phenol derivative and phenol is an effective germicide.

What does phenol give with $NaOH$ and $CHCl_3$ at $340 \ K$?

Which of the following compounds decolourises $Br_2 / H_2O$ and also gives a positive test with neutral $FeCl_3$?

Which of the following is the weakest acid?
