Why is (-)-butan-2-ol is optically inactive?

Open in App

Solution

$B u t a n - 2 - o l$ has asymmetric carbon (chiral center) with four different groups attached to the central carbon. As racemic mixture cancel each other out optically, such solutions do not rotate the plane polarized light, so they are optically inactive.

Why is (-)-butan-2-ol is optically inactive?

Butan−2−ol has asymmetric carbon (chiral center) with four different groups attached to the central carbon. As racemic mixture cancel each other out optically, such solutions do not rotate the plane polarized light, so they are optically inactive.
