Predict the products formed in the following reactions.
Predict the product(s) formed in the following reactions. If there is no reaction, write “No Rxn" as the answer for the major product and leave the minor product box blank. If there is no minor product in the reaction, then leave the minor product box blank. If there are multiple products, make sure the products are in the appropriate box. (24 points, 4 points each) Note: Do not over complicate some questions...

A. Consider the following pairs of structures. Designate each
chirality center as (R) or (S) and identify the
relationship between them by describing them as representing
enantiomers, diastereomers, constitutional isomers, or two
molecules of the same compound. Use handheld molecular models to
check your answers.
B. Tartaric acid
[HO2CCH(OH)CH(OH)CO2H] was an important
compound in the history of stereochemistry. Two naturally occurring
forms of tartaric acid are optically inactive. One optically
inactive form has a melting point of 210 − 212 °...

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....
