DATA:
- amount of product collected = 1.727 g
- boiling range: 130–135 °
QUESTIONS
- Was the reaction successful? What was the actual yield? (You may need to do some unit conversions for this)
- Comment on the boiling range. Can boiling range alone be used to confirm the identity of the product?
- Does the IR spectrum show expected signals for the ester? Point to specific stretches that are present in the product but not in the reactants.
Please answer and explain!
Homework Answers
Answer to Question no.1: Was the reaction successful? What was the actual yield? (You may need to do some unit conversions for this)
By only IR spectrum we can't conclude about the yield and successful conversion. Please provide the reaction condition also.
Answer to Question no.2: NO, You can confirm the formation of the product by checking its functional group test or by some spectral analysis, the boiling point result just guide you.
Answer to Question no.3: Yes, The IR streching bend at 1739.12 cm-1 is confirms the formation of ester.
simple esters come at ~1740-1760 cm-1,

Assign all signals in the diagnostic region (4000-1500 cm-1)
and strong signals (less than 40% transmittance) in the fingerprint
region (1500-500 cm-1). Create a spectral correlation table where
each signal is assigned to a bond type or functional group. Discuss
it in relation to the table you prepared for pre-lab
assignment.
