Chemistry Question on Haloalkanes and Haloarenes
Which of the following compounds are optically active?
A
1 and 2
B
2 and 3
C
3 and 4
D
1 and 4
Answer
2 and 3
Explanation
Solution
(1) and (4) compounds are meso-compounds, they possesses a plane of symmetry and is consequently optically inactive and superimposes on its mirror image (i.e., they are identical).
Optically active compounds are those that have the chiral molecule. A chiral molecule has all the four different substitutes. Secondary butyl amine is an optically active compound. As it has a chiral molecule.
