Question
Why is Butan-1-ol optically inactive but Butan-2-ol is optically active?
Advertisements
Solution
Butan-2-ol has a chiral centre, that is, butan-2-ol has a carbon atom bonded to four different substituents.
Thus, it is optically active. On the other hand, butan-1-ol does not have any chiral carbon atoms.
Therefore, it is optically inactive.
