Use the Data provide below to answer question 1, 2 and 3:
A Student is tasked with synthesizing butyl propanoate.
The volume of butanol used: 4.60 ml
The volume of propionic acid used: 7.50 ml
Weight of butyl propanoate submitted: Vial with product - Empty Vial
14.727 g - 14.106 g = 0.621 g
1. Based on the information above, calculate the theoretical yield in grams (Show work for full credit):
2. Calculate the overall percent yield, based on the information provided (show work: Show your complete percent yield calculation below. Clearly identify the limiting reagent. Watch significant figures).
3. A student submitted their synthesized ester with a boing point of 120o-130o C.
Based only on the observed boiling point (or range), was the compound obtained the specific ester you attempted to synthesize? Explain.

question
3 answer choices.
You add 0.58 mL of n-propanol (0.803 g/mL, 60.1 g/mol) to an excess of acetic acid to create the pear ester propyl acetate (102.1 g/mol). If you obtain 0.53 grams of the product, what was your percent yield? You react acetic acid with an unknown alcohol, and obtain the following NMR of the product. What is the unknown alcohol? 1.0 20 3.0 4.0 ppm (t1) 1-butanol (CH3CH2CH2CH2OH) O 2-propanol ((CH3)2CHOH) O 1-propanol (CH3CH2CH2OH)...
