Distinction between Alcohols and Phenols

Explain the litmus paper test with phenols and alcohols.

Test of phenol can be done by:

The structure of the compound that gives a tribromo derivative on treatment with bromine water is

Four hydroxy compounds have functional groups as shown.

$\left(\mathrm{A}\right)-{\mathrm{CH}}_2\mathrm{OH} \left(\mathrm{B}\right)-\underset{|}{\mathrm{C}}\mathrm{HOH} \left(\mathrm{C}\right)\mathrm{PhOH}\mathrm{ }\left(\mathrm{D}\right)\mathrm{Ph}-\underset{|}{\mathrm{C}}\mathrm{HOH}$

The purple colour $\mathrm{F}\mathrm{e}\mathrm{C}{\mathrm{l}}_3$ will be given by

Note: $\left(\mathrm{B}\right)$, $\left(\mathrm{C}\right)$ and $\left(\mathrm{D}\right)$ has modified.

Two aromatic compounds having formula ${\mathrm{C}}_7{\mathrm{H}}_8\mathrm{O}\mathrm{ }$which are easily identifiable by $\mathrm{F}\mathrm{e}\mathrm{C}{\mathrm{I}}_3$ solution test (violet colouration) are

Phenol can be distinguished from ethanol by the following reagents except

To distinguish between salicylic acid and phenol one can use

Phenol can be tested by
