Ortho, meta, and para-xylene (1,2-dimethylbenzene,
1,3-dimethylbenzene, and 1,4-dimethylbenzene) provide similar mass
spectra which are very different from ethylbenzene. Explain why you
would expect this based on the common fragmentation behavior of
arenes. What would you expect to be the main fragments observed
with ethylbenzene?
Explain why the methoxy group is a good activator and ortho-
para director in electrophilic aromatic substitution reactions. Use
resonance forms and the Wheland intermediate in your answer.
1. Instrumentation is a key aspect of chemistry and specifically
spectroscopy for organic chemistry. Why is spectroscopy the
preferred technique in your opinion? How does this make the field
of organic chemistry possible? In regards to mass spectra why is
this technique so useful? Why is it so versatile with the various
detectors it can be coupled with?
2. Studying about chemical separation techniques how do you see
chemical separations in everyday life? How do those separations
take place and...
In organic chemistry lab we just completled a "Lidocaine
Synthesis". I have some questions to clarify before we take the in
class exam.
1. Based on apperence and melting point; how can we validate if
the crystals are pure lidocaine?
2. When using the seperatory funnel in extraction, we washed the
organic layer with water and would shake then drain the aqueous
layer out. After a couple of washes with water, we then use HCL to
extract and collect this...
In organic chemistry lab, we separated a sample of benzion and
benzoic acid. We tested the purity of the samples we obtained using
a TLC plate. All of our benzoin spots also showed an impurity of
benzoic acid. However, our benzoic acid spot did not show an
impurity of benzoin. Why is this?

In an organic chemistry lab we were looking at the substrate and
nucleophile effects in Sn2 reactions. Our experimental data showed
that 1-bromobutane with 1.0mL of 0.25M NaI in 2-Butanone reacted
faster than 1-bromobutane with 1.0mL 0.50M NaI in 2-butanone. Also,
our experimental data showed that 1-bromobutane with 1.0mL of 0.50M
NaI reacted faster than 1-bromobutane with 2.0mL of 0.05M NaI.
These result are the opposite of the theoritcal rate aren't
they? From my understanding, the Sn2 reaction rate should...
Taken Organic Chemistry Second Edition! We are in the third
week, and I need a conclusion of of the report.
We are testing Aspirin Products
we used buffered aspirin, 10% of NaOH, 1% FeCl3
Can I get a conclusion of the report. Need this as soon as
possible.
