Chapter 12, Problem 12.2YT

Interpretation Introduction

Interpretation:

To write the racemic to each product that will be produced as a racemic mixture.

Concept introduction:

Stereochemistry is conserved in such reactions because both C-E bonds are formed simultaneously. Normally, a C=C double bond can lead to scrambling of the cis/trans relationship among the groups attached to those carbon atoms.

One stereoisomer is produced by the addition to the other face. If the initial alkene s chiral, then addition to each face of the alkene is equally likely. If the initial alkene is chiral, however, then it possesses no plane of symmetry, making electrophilic addition to one face more likely than addition to the other.
