Test
Tollens Reagent
Warm
silver nitrate
(AgNO3) + excess aqueous
NH3
(ammonia)
Aldehydes =
Silver
mirror is formed
Aldehydes = no
visible
change
Test
Fehling's solution
Blue
solution of Copper 2+ ions, aldehydes
reduce
the Copper 2+ ions to form a
red
/brown precipitate
aldehydes = form red/
brown
precipitate
ketones =
no
visible change
Aldehydes can be reduced back to
primary
alcohols
Ketones can be reduced back to
secondary
alcohols
This reaction takes place through
nucleophilic
addition
reducing agent =
NaBH4
