This is Organic Chemistry Lab, Solvent Extraction.
1. What are the criteria for solubility of organic molecules in
water?
2. If methylene chloride was used as the organic solvent in
solvent extraction, instead of ether, what would the top layer be
in the separation step?
3. What formula was used to calculate interaction of organic
compounds with the stationary phase?
4. In the given mixture (liquid-liquid), which compound (be
specific) has the weakest interaction with the stationary phase?
Why?

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...

We did Knoevenagel-Robinson experiment in organic lab. To check
for the product's purity (ethyl 3-coumarincarboxylate), we used the
thin layer chromatography technique. We dissolved a small amount of
the solid crystals in dichloromethane and added a drop of the
solution to a plate. Then, we ran the chromatography. We used two
mobile phases in two different beakers. One contained 10% ethyl
acetate/hexane solution and the other contained 20% ethyl
acetate/hexane solution. We put a plate containing a drop of the...

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?
