$A$ reaction of phenol with chloroform in the presence of sodium hydroxide to form salicylaldehyde is known as

The correct order of acidity of the above compounds is:

What is produced when phenol reacts with sodium?

When phenol is allowed to react with $Br_2$ in $(i)$ $CS_2$ solution and $(ii)$ in aqueous solution,the resulting compounds are

$A$ compound $A$ $(C_{7}H_{8}O)$ is insoluble in $NaHCO_{3}$ solution but dissolves in $NaOH$ and gives a characteristic colour with neutral $FeCl_{3}$ solution. When treated with bromine water,compound $A$ forms the compound $B$ with the formula $C_{7}H_{5}OBr_{3}$. $A$ is:

Given below are two statements: One is labelled as $Assertion$ $A$ and the other is labelled as $Reason$ $R$:
Assertion $A$: $pK_a$ value of phenol is $10.0$ while that of ethanol is $15.9$.
Reason $R$: Ethanol is a stronger acid than phenol.
In the light of the above statements,choose the correct answer from the options given below:
