Phenol and resorcinol are both resistant to mild oxidation.

Hydroquinone can under go mild oxidation by ammoniacal silver nitrate or "Tollen's Reagent".

Tollen's Reagent is a solution of diammine siver(I) ions:

#[Ag(NH_3)_2]^(+)(aq)#

They can be regarded as #Ag_((aq))^(+)#

Phenol is :

Resorcinol is 1, 3 dihydroxybenzene:

Hydroquinone is 1, 4 dihydroxybenzene:

This will undergo mild oxidation to benzoquinone:

In doing so silver(I) ions are reduced to metallic silver giving the characteristic "silver mirror".

#C_6H_4(OH)_2rarrC_6H_4O_2+2H^(+)+2e#

#2Ag^(+)+2erarr2Ag#
