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....

Which of the following statements about oxalic acid is true? a.) It is very soluble in water even in cold temperatures due to its low mass and ability to hydrogen-bond. b.) It reacts with water to form carbon dioxide and water. c.) It is only soluble in cold water but will precipitate out in hot water. d.) It has a lower melting point than most carboxylic acids so it melts when the solution is heated and thus cannot recrystallize. Thank...
