SLO-2.3. The student used sodium ethoxide with an optically-active, secondary alkyl halide with a specific rotation, in an aprotic solvent. The specific rotation is +32 degrees. What should be expected for the optical activity of the isolated product? 00.0°, from an elimination product +32°, since a reaction will not take place 0-32° 00.0°, from a racemic mixture of products

Học CH,Co? (5)-(1-bromopropyl)benzene (t)-1-phenylpropyl acetate The reaction of the chiral alkyl halide shown below with acetate gives a racemic mixture of acetate esters. A racemic product is formed in this reaction because O(S)-(1-bromopropylbenzene is a tertiary halide O(S)-(1-bromopropyl)benzene is a chiral molecule acetate is a weak nucleophile the reaction has occurred via a carbocation intermediate acetate is good nucleophile

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....
