Q. Which of the following molecules can exhibit optical activity?

KVPYKVPY 2015Organic Chemistry – Some Basic Principles and Techniques

Solution:

Optical activity can be exhibited only by those molecules, which have chiral centre.
(a) $\underset{\text{1-bromopropane}}{CH_3 —CH_2—CH_2—Br}$
No chiral centre present thus, it will not exhibit optical activity.

As there is the presence of one chiral centre (*), so it will exhibit optical activity
image
It is optically inactive
image
It is also optically inactive.
