What's the difference between acetamide and ethanamide?
Acetamide
Definition:
(n.) A white crystalline solid, from ammonia by replacement of an equivalent of hydrogen by acetyl.
Example Sentences:

(5) Pyridyl-biphenylyl-acetamide (diphenpyramide, Z-876) is a new bisphenylalcanoic derivative with marked anti-inflammatory, analgesic, antipyretic and uricosuric properties.
(6) The prototype kappa-selective agonist, PD117302 (trans-N-methyl-N-[2-(1-pyrrolidinyl)cyclohexyl]benzo[b]thiophene-4- acetamide, 2) has been regio- and stereoselectively substituted in the C-4 and C-5 positions of the cyclohexyl ring with the methyl ether and spiro tetrahydrofuran groups.
(7) For N-methyl acetamide, N,N-dimethyl acetamide and the corresponding formamide derivatives, H-abstraction occurred only from the N-methyl group.
(8) The apparent first order rate constant for inactivation is proportional to the concentration of iodoacetamide and a second order rate constant of 37 M-1 min-1 is obtained at pH 6.8 and 25 degrees C. Cyanogen bromide fragmentation of iodo(1-14C)acetamide - modified inactivated Dopa decarboxylase followed by trypsin digestion yields a single radioactive peptide.

(10) In the same series one dialkylamino-acetamide derivative shows excellent trypanocidal activity in the NMRI mouse, but this effect is limited to Trypanosoma brucei; 12 preparations developed a trypanocidal effect only after relatively high doses; their range of efficacy included Trypanosoma cruzi, among others, after repeated treatment.
(11) This K+ effect is specific for ouabain induction, since induction by other inducers, such as dimethyl sulfoxide and dimethyl acetamide, does not exhibit this marked sensitivity to the levels of K+ ions in the culture medium.
(12) The effects of halogenated acetamides were studied in more detail and results of studies on the interaction of iodoacetamide with cellular constituents are presented.
