Material and Methods * Osmosis : -thistle funnel tube -dialysis tubing sack -saturated NaCl w/food coloring -beaker with distilled H2O The experiments begins with the construction of a simple osmometer by obtaining pre-soaked length of tubing ‚opened and tied at the end. The tube is filled with saturated NaCl solution (with added food coloring) and the thistle is inserted in the dialysis tubing. The dialysis tubing is sealed to the thistle funnel with dental floss and placed in a beaker filled

contents of the beaker to dislodge any precipitate from the sides. Then‚ pour the content of the beaker into the filter paper-lined funnel carefully. Afterwards you will need to measure out 2 to 5mL of distilled water into a graduated cylinder. Pour it down the sides of the beaker‚ swirl‚ and pour into the filter paper-lined funnel. Once all the liquid has drained from the funnel‚ lay the filter paper containing the precipitate on folded layers of paper towels and set it somewhere to air-dry. Once the filter

The Grignard Synthesis of Triphenylmethanol Abstract: Grignard synthesis of triphenylmethanol was achieved by use of the Grignard reagent phenyl magesium brominde. The organometallic grignard reagent was synthesized by use of a reflux apparatus recrystallization techniques. Once synthesized it was used in a Grignard reaction that involved nucleophilic addition to a carbonyl in order to make triphenylmethanol. The final product was solidified and recrystallized and spectral data was

Experiment 4: Isolation of Essential Oils from Eugenol Background: Anyone who has walked through a forest or who enjoys the variety of fragrances that flowers have to offer knows that many plants and trees have their own distinctively pleasant odors. These odors are due to the volatile essential oils‚ many of which have been prized commodities since ancient times. If a list of commercially important essential oils was compiled the list would exceed 200 essential oils. Thyme‚ garlic‚ peppermint

A. Goal and Purpose: Session 1: In this lab‚ we will achieve a simple Friedel-Crafts alkylation of anthracene. The choice of anthracene as an aromatic substrate stems from two considerations. First‚ there is a question of regioselectivity. Second‚ anthracene and its derivatives are highly visible under UV light. Session 2: In this lab‚ we will complete a partial conversion of 9-acetylanthracene using m-chloroperoxybenzoic acid (mCPBA). We will also determine by NMR‚ the regiochemistry of the
