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…
