Interpretation Introduction
Interpretation:
The stereoisomeric properties of the products of chlorination of
Concept introduction:
Stereoisomers are characterized for the molecules that have same molecular formula and arrangement of atoms but differ in the spatial orientation of groups in the molecule.
Stereoisomers are further divided into enantiomers and diastereomers. Diastereomers are the stereoisomers that are non-superimposable and non-mirror images of each other.
A meso isomer, or the meso compound, is a stereoisomer which has a superimposable mirror image.
A meso compound is optically inactive due to presence internal compensation

• PRACTICE PROBLEM 6.6 S 2 reactions that involve substitution at a chirality center can be used to relate the
configuration of one molecule to another, because we know the SN2 reaction will occur
with inversion.
(a) Illustrate how this is true by assigning R,S configurations to the 2-chlorobutane
enantiomers based on the following data. [The configuration of (-)-2-butanol is given
in Section 5.8C.]
HO-
(+)-2-Chlorobutane
(-)-2-Butanol
SN2
[a]3 = +36.00
(Enantiomerically pure)
[a] = -13.52
(Enantiomerically pure)

(b) When enantiomerically pure (+)-2-chlorobutane is allowed to react with potassium
iodide in acetone in an SN2 reaction, the 2-iodobutane that is produced has a minus
optical rotation. What is the configuration of (-)-2-iodobutane? Of (+)-2-iodobutane?
Review Problem 5.2

yourself that they are not mutually superposable. (a) Make similar models of 2-bromo-
propane. Are they superposable? (b) Is a molecule of 2-bromopropane chiral? (c) Would
you expect to find enantiomeric forms of 2-bromopropane?
