Atomic grouping
Suffix	-amide
Position in chain	only at end of chain
General formula	CnH2n+1NO
Common family name	amide

Notes:

• Since the suffix (-amide) has an initial vowel, the terminal -e of the alkane name is dropped before the suffix is added.

• The carbonyl group in tha alkanamide family is always at the end of a carbon chain and as such is always position 1. As with the alkanals, the locant (1) is omitted.
  pentanamide, NOT pentan-1-amide.

  Examples :

  Structure	IUPAC Name	Model
  	methanamide (aka formamide)
  	ethanamide (aka acetamide)
  	hexanamide
  	3-oxopentanamide
  	(E)-hept-2-enamide

  As in the case of the alkanamines, the two hydrogens on the nitrogen may be replaced by carbon residues without radically changing the chemical nature of the compound. Thus the family alkanamide contains the N- substituted compounds in addition to C-substituted compounds. The locant, N, is used to indicate a substituting group on the nitrogen atom.

  Structure	IUPAC Name	Model
  	N,N-dimethylmethanamide (DMF)
  	N-ethyl-N-methylpropanamide
  	N,N,4-triethylhexanamide
