Q. Phenol can be distinguished from ethanol by the following reagents except
A) Sodium
B) $NaOH/I_{2}$
C) Neutral $FeCI_{3}$
D) $Br_{2}/H_{2}O$
Explanation
(a)
Phenol cannot be distinguished from ethanol by sodium because both evolve hydrogen with sodium.
$2C_{6}H_{5}OH + 2Na \rightarrow 2C_{6}H_{5}ONa + H_{2} \uparrow$
$2C_{2}H_{5}OH + 2Na \rightarrow 2C_{2}H_{5}ONa + H_{2} \uparrow$
