Reduction of Ketone
During this experiment we had to reduce 9-fluorenone to
9-fluorenol. We took pure fluorenone and fluorenol and mixed with
acetone then spotted them on lanes one and two on our TLC plate. We
then took 9-fluorenone and and mixed with methanol, and began
mixing. We then spotted the methanol fluorenone mixture on our TLC
plates in different time intervals, lane three 0 seconds, lane four
30 seconds, lane five 60 seconds, lane six 120 seconds, lane seven...

Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....
