unknown solid organic chemistry 2 experiment, please help in determining my solid Here's my data so far, I'll be continuing next week: -Melting point of the unknown is 209-215 degrees C -Solid unknown itself is a white crushed powder with a strong smell -Insoluble in 5% NaOH, Water, 5% HCl but soluble in H2SO4 and 95% ethanol -Negative DNPH test with no precipitate -Positive chromic acid test with a green precipitate So i'm thinking i received a borneol compound. How...

Organic Chemistry Lab question In the experiment we did acid-base extractions to find impurities. The impurity was either benzoic acid (acid) or 4-chloroaniline (base) So in this experiment we did Acid-Base extraction with an unknown compound. So we had an unknown of 0.150 grams and mixed it with 20 mL of diethyl ether. We placed this in a separatory funnel and added 2mL of 1.0 NaOH solution to the separatory funnel and placed the stopper over the top of the...

PreLab - ID of Liquid Unknown 1. A liquid which is soluble in water, 5% aq. NaOH and 5% aq. HCl is suspected of being an amine. What feature of the solubility tests would confirm whether or not it is an amine? Explain. 2. While the effect is generally small enough to he neglected, what variable of laboratory conditions can alter the measured boiling point temperature of the liquid? 3. Match the letter of the functional group to the description...
