A) Can the experiment of green extraction of the trymyristin from the nutmeg can be considered as ‘ green chemistry’.?
B) During the same experiment, which is better to use, water condenser or waterless condenser and why?
Homework Answers
A) Yes, it can be considered as green chemistry because it has-
-Average economic efficiency.
- Low (eco)toxicological risks.
-Low environmental persistence for most of the substances.
B) In this experiment, water condenser is used because this allows the condenser columns to be very cold such that any vapours given off are cooled back to liquid, and fall back to the reaction vessel.

In today's experiment you will synthesize the a,ß-unsaturated ketone from 3- nitrobenzaldehyde and acetophenone via an aldol condensation. Once the aldol product forms, the reaction spontaneously dehydrates to the conjugated enone. This reaction fulfills some of the principles of green chemistry in that it has high atom economy, produces water as the only major byproduct, and uses ethanol as a non-toxic solvent. ON NaOH Etон Ph Which aldehyde will work better in this reaction as an electrophile: 4-cyanobenzaldehyde or 4-methoxybenzaldehyde?...

We used the technique of extraction in this lab. After extraction, what was left in solution? Why is it acceptable for those chemicals to be left to sit for a week? Think about the possible reactions that would or would not occur during the week? In our extraction, we used NaCl solution. Why did we choose to use that vs. water? In this experiment, we did a Fischer Esterification using excess acetic acid, isopentyl alcohol, and sulfuric acid to form...

Introduction: Pre-lab Questions Turn in typed responses in the beginning of lab. Answer in complete sentences. Show your work in pen where applicable. 1. What other compounds are extracted along with caffeine into the tea? Use what you know about the relative polarity of the functional groups within these compounds to determine the final destination of the following compounds: cellulose, tannins, chlorophylls, sodium carbonate. Do the majority of these compounds end up in the tea bag, filtered solid, aqueous layer,...
