Phenol on heating with $CHCl_3$ and $NaOH$ gives salicylaldehyde. The reaction is called

The reaction,
$C_6H_5OH + CHCl_3 \xrightarrow{NaOH/\Delta} \text{o-hydroxybenzaldehyde} + H^+$
is known as:

Identify $A$ in the following reaction: $A + \text{Acetic anhydride} \xrightarrow{H^{+}} \text{Aspirin} + \text{Acetic acid}$

The major product of the following reaction sequence is:
Aniline $\xrightarrow[(i) NaNO_2, HCl, 273-278K]{(ii) H_2O, warm} \text{Product}$ $\xrightarrow[(iv) NaOH]{(iii) Br_2, (excess)} \text{Product}$ $\xrightarrow{(v) CH_3I} \text{Final Product}$

Match List-$I$ with List-$II$:

List-$I$ (Compound)	List-$II$ ($pK_a$ value)
$A$. Ethanol	$I$. $10.0$
$B$. Phenol	$II$. $15.9$
$C$. $m$-Nitrophenol	$III$. $7.1$
$D$. $p$-Nitrophenol	$IV$. $8.3$

Choose the correct answer from the options given below:

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