Which of the following compounds are optically active and why? (1) `CH_(3)CHBrCH_(2)CH_(3)`
(2) `(CD_(3))_(2)CHCH_(2)CH_(3)`

Text Solution

Verified by Experts

The compound contains one asymmetric C - atoms `(CH_(3)CHBrCH_(2)CH_(3))`. So it is not superimposable on its mirror image and hence, it is optically active.
(2) The molecule has a plane of symmerty and it is superimposable on its mirror image. Therefore, it is optically inactive.
(3) The molecule is not superimposable on its mirror image. So, it is optically active.
(4) The molecule is not superimposable on its mirror image. So, it is optically active.
This planar compound is superimposable on its mirror image. So, it is optically inactive.
