# Writing an equation for a ester formed through reflux

1. The problem statement, all variables and given/known data

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

2. Relevant equations

chemical equations

3. 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
