Question
Chapter 14, Problem 24P
Interpretation Introduction
Interpretation:
Define racemic mixture and suggest about is optically activity.
Concept Introduction:
A compound or substance is said to be optically active if it is able to rotate plane of polarized light. There are two possibilities that a stereoisomer is not optically active, internal compensation and external compensation.

Which of these structures is chiral?
Draw the correct structure for (2S,3R)-2,3-diiodopentane. Show stereochemistry clearly. To ensure proper grading, explicitly
draw all four groups, including wedge/dash bonds, around a chirality center. Indicate whether the compound could exist in an
optically active form.
