Discussion Overview

The discussion revolves around writing a chemical equation for the formation of an ester through the reflux of 3-methyl-1-butanol and ethanoic acid. Participants also seek to determine the systematic name of the ester produced, exploring concepts related to esterification.

Discussion Character

  • Homework-related
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant describes the reaction setup involving 3-methyl-1-butanol and ethanoic acid, noting the distinct banana smell of the ester formed.
  • Another participant suggests reviewing "Fisher Esterification," indicating that the reaction involves an alcohol and a carboxylic acid yielding an ester.
  • There are attempts to formulate the chemical equation, with one participant expressing uncertainty about how to proceed with the problem.
  • A later reply provides a general equation for ester formation, indicating the production of water and an ester represented as R1COOR2.
  • Participants discuss how to derive the systematic name of the ester, with one providing a specific example of the ester structure as CH3COOCH2CH2CH(CH3)2.

Areas of Agreement / Disagreement

Participants generally agree on the process of esterification and the components involved, but there is no consensus on the exact systematic name of the ester formed, as this remains a point of inquiry.

Contextual Notes

Some participants express uncertainty regarding chemical equations and systematic naming conventions, indicating a potential gap in foundational knowledge about esters and their formation.

Who May Find This Useful

Students studying organic chemistry, particularly those focusing on esterification reactions and chemical nomenclature.

Homework Statement



write an equation for the reaction and state the systematic name of the ester formed

3-methyl-1-butanol was mixed with ethanoic acid and refluxed for approx. 40 mins

the mixture was washed in a separating funnel with distilled water, then sodium carbonate, then distilled water again.

The organic layer of the isolation was put inside a conical flask with calcium chloride and allowed to sit

then the mixture was distilled and finally I collected only the fraction that come after 120 degrees (c)

The ester had a distinct banana smell

Homework Equations



chemical equations

The Attempt at a Solution



(CH3)2CHCH2CH2OH + CH3COOH → ?1

?1 + CaCl2 → ?2

I'm really not sure how I'm supposed to do this problem, and I'm terrible with chemical equations. Can anyone help me out with this problem?

Review "Fisher Esterification". Alcohol plus carboxylic acid yields ester.

(ch_3)_2chch_2ch_2oh + ch_3cooh => h_2o + r_1coor_2

Thanks for that seems to make sense now that I've read through my textbook. I missed the classes that were on esters so I was kind of lost.

How would I get a systematic name of the organic compound formed from this?

the esther (R1COOR2) above is general. In your example:

CH3COOCH2CH2CH(CH3)2

then you can name the esther
