SR Amines

Question 1

Primary amine => Secondary Amine

Equation
Type of reaction
Conditions
Reagents

Answer 1

Equation
-Step one
Primary amine + Haloalkane -> alkylammonium salt
-Step two
Alkylammonium salt + NaOH -> Secondary amine + NaCl +H2O

E.g. Propylamine + chloropropane -> dipropylammonium chloride salt
Dipropylammonium salt + NaOH -> dipropylamine + NaCl + H2O
Reagents
Haloalkane then NaOH

Question 2

Secondary Amine => Tertiary Amine

Equation
Type of reaction
Conditions
Reagents

Answer 2

Equation
-Step one
Secondary amine + Haloalkane -> alkylammonium salt
-Step two
Alkylammonium salt + NaOH -> Tertiary amine + NaCl +H2O

E.g. Dipropylamine+ chloropropane -> tripropylammonium chloride salt
Tripropylammonium salt + NaOH -> Tripropylamine N(CH3CH2CH2)_3 + NaCl + H2O

Reagent
Haloalkane then NaOH
