Chemistry - ALCOHOL & ETHER Question with Solution | TestHub

With neutral${\text{FeCl}}_{\text{3}}$solution, phenol gives violet colour solution but${\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}\text{OH}$does not give this test.

Phenol cannot be distinguished from ethanol by sodium because both evolve hydrogen with sodium.
$2{\mathrm{C}}_6{\mathrm{H}}_5\mathrm{O}\mathrm{H}+2\mathrm{N}\mathrm{a}\to 2{\mathrm{C}}_6{\mathrm{H}}_5\mathrm{O}\mathrm{N}\mathrm{a}+{\mathrm{H}}_2\uparrow$
$2{\mathrm{C}}_2{\mathrm{H}}_5\mathrm{O}\mathrm{H}+2\mathrm{N}\mathrm{a}\to 2{\mathrm{C}}_2{\mathrm{H}}_5\mathrm{O}\mathrm{N}\mathrm{a}+{\mathrm{H}}_2\uparrow$
