Question

Simple chemical test that would distinguish between (1) allylamine and propylamine (2) tripropylammonium chloride and tetrapropylammonium chloride

Answer 1

distinguish between (1) allylamine and propylamine

Reaction of allylamine and propylamine with HCl

Allylamine react with two mole of HCl

CH₂=CH-CH₂-NH₂ + 2 HCl $\mapsto$ CH₃-CH(Cl)-CH₂-NH₃⁺Cl^-

Propylamine react with one mole HCl

CH₃-CH₂-CH₂-NH₂⁺ Cl^-

(2) tripropylammonium chloride and tetrapropylammonium chloride

Tripropylammonium chloride react with NaOH give acid -base reaction is

Tetra ammonium chloride not give reaction with NaOH
