Out of the two compounds $A$ ($p$-nitrophenol) and $B$ ($o$-nitrophenol) shown below,the vapour pressure of $B$ at a particular temperature is expected to be:

Which of the following reactions is used to obtain salicylic acid from phenol?

Consider the following reaction sequence:
$\text{Compound } (x)$ $\xrightarrow[(ii) H_3O^{+}]{(i) CO_2, NaOH, 120^{\circ}C, \text{high pressure}} \text{Compound } (y) \text{ (Major Product)}$
$[76.6\% C, 6.38\% H, \text{vapour density } 47]$
Compound $(y)$ develops a characteristic color with neutral $FeCl_3$ solution.
Identify the $INCORRECT$ statement from the following for the above sequence.

In the presence of $NaOH$,phenol reacts with $CHCl_3$ to form $o$-hydroxybenzaldehyde. This reaction is called:
