- 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…Please answer the question at the bottom, Thanks.

- what is the theoretical mass of the product? synthesis of Dibenzalacetone (A)In this lab you will need to determine the amounts of the reactants you will use. We will use 0.0125moles of acetone. You need to: (1) convert this into a volume in mL, (2) Calculate the number ofmoles of benzaldehyde needed based on the balanced chemical reaction, (3) Convert the number ofmoles of benzaldehyde into volume in mL. Your reagent table should reflect your calculated values. Mix the benzaldehyde and acetone based on the volumes from your prelabcalculations in a testtube. Add 25 mL of 10% NaOH solution to a 125 mLErlenmeyer flask along with a stir bar and 20 mL of ethanol. Make sure thetemperature of the solution in the flask is below 25 C before proceeding. Add half ofthe solution from your test tube to the flask. Allow the solution to stir for 15 minutesand then add the remainder of the solution. Rinse the test tube with ethanol and allowthe solution to stir for an additional 30 minutes.…What is the limiting reactant and theoretical yeild of this Chemiluminescent Reaction? The reaction uses 4ml of a 0.6M phenol (4-methylphenol), 1.2 mL of oxalyl chloride and 0.35 mL of triethylamine1-butanol yields 1-bromobutane in the presence of concentrated sulfuric acid and an excess of sodium bromide. CH3CH2CH2CH2OH (l) → CH3 CH2CH2CH2Br (l) If 15.89 mL of 1-butanol produced 12.23 g of 1-bromobutane, the percentage yield of the product equals: (Assume the density of 1-butanol is 0.81 g/mL, the molar mass of 1-butanol is 74 g/mol, and the molar mass of 1-bromobutane is 137 g/mol.) %
