in
recrystallization of acetanilide experiment, i got a recovery yield
of 10% and percentage yield of 4%. My NMR of the revovered product
looks clean except for an extra peak that looks like acetic acid
from the reaction. However an OH peak of the acetic acid is
missing... please explain what the peaks could be and why my yields
are ao low but other test seem to prove the compound was pure

in
a synthesis of acetanilide experiment, i performed
recrystalization. i used my recovered product to test for
impurities. My TLC and melting point analysis seems as if there are
no impurities however my nmr shows an impurity maybe consistent
with hydrolysis of acetanilide. (50mg was mixed with 400
microliters of deuterated chloroform for NMR) the impurity that im
talking about can be seen below with label “figure this out”
is the peak because hydrolysis?
When could have hydrolysis happened and...

please help explain the nmr below...
hydrolysis of acetanilude was taking place
-WHERE IS THE PEAK AROUND 8PPM COMING FROM AND WHY IS IT
BROAD.
-IS THE SMALL PEAK FROM ACETIC ACID
-WHY IS THE INTEGRATION IN THE AROMATIC REGION 7 and not
5?
please label which proton environment is what.

Please help. I need a step by step solution to find the
compound. I'm not too confident with what m/z means and how to read
the IR graph yet. What does quin (5) have to do with 2.36 ppm in
the H NMR? A description about those would be great too. Thank you
so much.
