Carbylamine test is a test for the detection of primary amines. In this test, the analyte is heated with alcoholic potassium hydroxide and chloroform. If a primary amine is present, the isocyanide (carbylamine) is formed which are foul smelling substances.
CH3NH2 + CHCl3 + 3KOH + 3KCl + 3H2O
Among the following, the correct order of basicity is :
NH2- > OH- > RO- > RCOO-
NH2- > RO- > OH- > RCOO-
RCOO- > NH2- > RO- > OH-
RCOO- > RO- > NH2- > OH-
