Introduction

Get ready to simplify your study of Amines! These mnemonics will make understanding the different types of amines, their reactions, and tests both fun and easy to remember. With memorable phrases, you'll be able to grasp complex concepts quickly and effectively.

Mnemonics: Amines | Chemistry Class 12 - NEET

Classification of Amines

Mnemonic: "P.S.T. - Parent, Sister, Twins"

  • P: (Parent) = Primary Amine (One carbon attached to nitrogen). The Parent (Primary) is the first one, just one "carbon" child (i.e., one alkyl group).
  • S: (Sister) = Secondary Amine (Two carbons attached to nitrogen). The Sister (Secondary) has two children, i.e., two alkyl groups attached to nitrogen.
  • T: (Twins) = Tertiary Amine (Three carbons attached to nitrogen). The Twins (Tertiary) have three children, i.e., three alkyl groups attached to nitrogen.Mnemonics: Amines | Chemistry Class 12 - NEET

Hinsberg Test

Primary and secondary amines react; tertiary amines don't.
  • Mnemonic: "Hin’s Perfectly Selected Targets"
  • Hin’s Perfectly Selected: Hinsberg test distinguishes Primary and Secondary amines.
  •  Targets:Tertiary amines don’t react.Mnemonics: Amines | Chemistry Class 12 - NEET

Carbylamine Test

Only primary amines give the carbylamine reaction to give Isocyanides.

  • Mnemonic: "Potatoes Cook Slowly In Kitchen."
  • Potatoes: Primary amines react.
  • Cook: Use of Chloroform (CHCl3) as a reagent.
  • Slowly: Produces a Smelly product (isocyanides).
  • In: Forms Isocyanides as the product.
  • Kitchen: Requires KOH (alcoholic potassium hydroxide).

Hoffman Bromamide

The Hofmann Bromamide Reaction is a chemical reaction in which primary amides are converted to primary amines by the action of bromine in an alkaline solution, with the loss of a carbonyl group as carbon dioxide (CO₂).

  • Mnemonic: "Horrible Birds Always Attack Painlessly."
  • Horrible : Hofmann (the name of the reaction).
  • Birds : Bromine (the key reagent).
  • Always: Amides (the starting compound, primary amides).
  • Attack: Alkaline (the reaction occurs in an alkaline medium).
  • Painlessly: Referring to the formation of Primary amines, which are the product of the reaction.
