Match the compounds in Group-$I$ with their uses in Group-$II$. Find the correct match for Group-$I$ from Group-$II$.

Group-$I$ (Compound)	Group-$II$ (Use)
$A$. Alcohol	$1$. Antiseptic
$B$. Phenol	$2$. Perfumes
$C$. Ether	$3$. Detergents
$D$. Amine	$4$. Dyes

Which of the following statements are correct for phenol?
$(A)$ In general,phenol is more acidic than alcohol.
$(B)$ Phenol is used in the production of melamine plastic.
$(C)$ Phenol gives violet colour with neutral ferric chloride solution.
$(D)$ Phenol when heated with acetyl chloride gives phenetole.

Match the following column:

Column-$I$ (Reaction)	Column-$II$ (Electrophile)
$A$. $C_6H_6 + CH_3Cl \xrightarrow{AlCl_3} C_6H_5CH_3$	$P$. $CO_2$
$B$. $C_6H_5OH + CO_2 \xrightarrow[H^+]{NaOH} \text{Salicylic acid}$	$Q$. $:CCl_2$
$C$. $C_6H_5OH + CHCl_3 \xrightarrow{KOH} \text{Salicylaldehyde}$	$R$. $\stackrel{+}{C}H_3$
$D$. $C_6H_6 + SO_3 \xrightarrow{H_2SO_4} C_6H_5SO_3H$	$S$. $\stackrel{+}{S}O_3H$
	$T$. $SO_3$
