Vedclass · Answer

(D) $1$. The molecular formula $C_6H_6O$ corresponds to the degree of unsaturation $U = 6 - \frac{6}{2} + 1 = 4$, which suggests an aromatic ring.$2$. The compound dissolves in $NaOH$, indicating it is acidic in nature.$3$. It gives a characteristic violet colour with neutral $FeCl_3$, which is a standard test for phenolic groups.$4$. It reacts with bromine water to form a tri-bromo derivative $(2,4,6-	ext{tribromophenol})$, which is characteristic of phenol due to the strong activating effect of the $-OH$ group.$5$. Therefore, the compound is phenol.

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	$IV$. $8.3$
