Elimination Lab Report-2

Please answer the question at the bottom, Thanks. LAB NOTES FOR PREPARATION OF BUTYL MAGNESIUM BROMIDEAND ITS SUBSEQUENT CONVERSION TO AN ALCOHOL To the reaction flask were added 2.5967 gram of magnesium turnings, about 20 mlof diglyme, and a solution of 13.5942 gram of butyl bromide in about 25 mldiglyme.The procedure as per the lab manual was initiated. After the required heating timewas completed the reaction mixture was allowed to cool to room temperature.Then a solution of 6.1123 gram of acetone in about 15 ml of diglyme was addeddropwise as per the lab manual.The rest of the lab manual procedure was completed, ultimately affording 2.5532gram of an oily, clear and slightly yellow liquid, presumed to be 2-methyl-2-hexanol. Boiling point as measured by distillation was 138 – 141 deg C.About 0.8 ml of the presumed 2-methyl-2-hexanol was placed in an NMR tube towhich was added 2 drops of TMS. The tube was capped, then inverted and righted20 times to thoroughly mix the product and…

Answer the following questions following a Solubility and recrystalization lab for organic chemisty.  1. In a solubility and recrystallization lab you are working with the following chemicals : solids (benzoic acid, acetanilide,naphthalene, and resorcinol) and three solvents (water, ethanol and petroleumether) discuss and rank the polarity of the solvents and the polarity of the compounds being investigated. 2. Briefly describe how a mixture of sand and benzoic acid (soluble in hotwater) could be separated to produce pure benzoic acid.

10) Write an equation for the reaction of n-propyl magnesium chloride and butanal (Not 3- methylbutanal). Why was it important to have dry equipment that was heated in oven and a drying tube placed on top of the condenser for the above-mentioned reaction? Explain?

Could I please get some help with questions 7 and 8? Thank you!

What factors during the experiment caused the percent yield to be different than 100%? What impurities may be present in the final product (look at the spectroscopic data for evidence of this), and how does that effect the percent yield calculation? I got 64% for the percent yield.

Please answer this NEATLY, COMPLETELY, and CORRECTLY for an UPVOTE. 1-butanol, 2-butanol, and diisopropyl ether all tested negatve (immiscible) in the solubility test with concentrated H2SO4. Considering the structure of the compounds, what generalization can be made for a substance to be soluble in concentrated H2SO4?

STARTING WITH 18MG OF 2-methyl-2-butanol JUST B PLEASE  (b) theoretical volume of alkene mixture (ml) expected to be obtained in this experiment.

15. Please help me answer this organic chemistry question

Explain some of the hazards (name at least three) involved in the (Dehydration of Cyclohexanol – Synthesis of Cyclohexene) experiment. What are some necessary safety precautions when working with sulfuric acid?

Draw a flowchart showcasing the purification step done for the reaction under basic conditions (the basic reaction of 4-methoxyacetophenone with bleach, sodium hydroxide, and acetone), starting from the crude reaction mixture all the way to the isolated solid product. Assume for this drawing that the reaction was complete, and that none of the intermediates are found in the crude mixture. There may still be however traces of your starting material in the crude mixture, along with any excess reagents

6. Write down the structures of the products X and Y formed for the reactions below. excess 1-bromo-2-methylpropane 80 1. excess Mg 2. 3. H₂O* 13C of X 60 50 OH X 30 20 40 PPM the structures of the products formed for the reactions shown below? ....

Just want to make sure i am drawing the corret starting material before i submit. In this lab exercise would it be the hex-1-ene?

Was this experiment green and were the solvents safe? Could other have alternatives been used (including less solvent)? Was this energy Intensive?

Suppose you took your two compounds, dissolved them in tertbutyl methyl ether and then added them to a separatory funnel.  Now suppose you add in aqueous sodium bicarbonate and vigorusly shake the contents of the separatory funnel. ethanol will be dissolved in tert butyl methyl ether ether and valeric acid will be dissolved in the aqueous sodium bicarbonate layer. Draw the EXACT chemical structure that will exist in each of the layers after shaking with sodium bicarbonate.  (Is it neutral or charged?)

2. READ THE DIRECTIONS TO EACH QUESTION CAREFULLY - not following the directions means you get the question wrong! 3. FORMAT YOUR ANSWERS AS DIRECTED - formatting your answers incorrect means you get the question wrong! 4.
