Amines

an ammonia molecule in which one or more H atoms are substituted by alkyl or aromatic groups

Organic derivatives of Ammonia

They’re classified according to how many alkyl groups replace the hydrogens of ammonia

This is a slightly different classification scheme than used in alcohols:

Just like alcohols, tertiary ones aren’t as reactive

Tertiary has the highest melting and boiling point, and are the least polar

They can be main chains or side groups

Amines have priority over straight chain alkanes only

Nomenclature for Amines

The IUPAC system for amines are:

  1. Select longest carbon chain bound to the N as the parent chain
  2. Name chain by changing alkane name for the chain
    1. Drop the ‘e’ and add ‘amine’
  3. Number the chain and give the N the lowest numbering
  4. The number and identity of other substituents (including any of the main chain) are indicated at the beginning of the amine name (some are attached to N)
