2, 4 - Dinitrophenylhydrazine Test

Positive = Aldehyde or Ketone

Orange PPT

Chromic Acid Test

Positive = Aldehyde

Blue green solution from an orange-red solution

fast < 1 min

Ketones react way longer, alcohols and phenols also give positive results

Ferric Chloride Test

Positive = Phenol

Yellow color to a green/black color for + result

Ceric Ammonium Nitrate (CAN) Test

Positive = Alcohols

Yellow → Orange/Red

Hydroxamate Test

Positive = Esters

Purple solution is positive from reaction with FeCl3 solution

Copper Sulfate Test

Positive = Amine

Turns a blue-green or solid from a blue solution

*Do NOT test for solubility with H2SO4

Solubility Test

Water, Ether, HCl, NaOH, NaHCO3, H2SO4

Beilstein Flame Test

Positive = Halide

Green flame

Tests for Alkenes and Alkynes
