Answer:
IUPAC name literally is a chemical organic name given to an organic compound bashing on the IUPAC naming rules.
• Brady's reagent → 2,4-dinitrophenylhydrazine
It is used to confirm presence of carbonyl compounds (compounds with a carbonyl carbon).
• Tollen's reagent → Silver ammonical nitrate solution
It is used to distinguish between terminal and non-terminal alkyns (compounds with carbon to carbon tripple bonds)
• Fehling's solution → Copper (II) sulphate and Silver nitrate solution [ Copper (I) nitrate solution ]
It is used to distinguish between alkanols and aldehydes.
Also it distinguishes between terminal and non terminal alkyns
