SUMMARY

Ethanamide (CH3CONH2) reacts with ethanol (CH3CH2OH) to form an ester (CH3COOCH2CH3) and ammonia (NH3) under acidic conditions. The reaction requires concentrated sulfuric acid (H2SO4) in larger than equimolar amounts, as the acid is not catalytic but necessary for the reaction to proceed. This process mirrors transesterification, and it is crucial to distinguish between an amide and a primary amine during the reaction. The presence of sodium hydroxide (NaOH) could also facilitate the reaction, although it was overlooked in the discussion.

PREREQUISITES
  • Understanding of esterification reactions
  • Knowledge of amide and primary amine structures
  • Familiarity with the role of acids in organic reactions
  • Basic principles of transesterification
NEXT STEPS
  • Study the mechanism of esterification reactions involving amides
  • Research the properties and reactions of primary amines
  • Learn about the role of concentrated sulfuric acid in organic synthesis
  • Investigate the use of sodium hydroxide in organic reactions
USEFUL FOR

Chemistry students, organic chemists, and anyone interested in understanding esterification processes involving amides and alcohols.

Homework Statement



does ethanamide react with ethanol forming an ester?!

Homework Equations



CH3CONH2 + CH3CH2OH -------> CH3COOCH2CH3 + NH3

The Attempt at a Solution

 
Physics news on Phys.org
Under acidic conditions, amides can be esterified in exactly the same manner as transesterification can occur. The product is an ammonium chloride so acid is not catalytic but must be present in larger than equimolar amounts.
 
awww... i put only a few drops of concentrated H2SO4...

but it's only 2 marks...nvm

we had to distinguish between an amide and a primary amine.
i had completely forgotten about the NaOH reaction which could have been used...

thnks
