Symmetry and Optical Activity: Do Your Molecules Have It?

The video tutorial explains the concept of the center of symmetry in molecules, where a point allows for equidistant lines to meet similar groups or atoms, making the molecule symmetric and optically inactive. It uses the example of an A6 pointed star to illustrate symmetry. The tutorial also covers the N fold alternating axis of symmetry, where a molecule rotated and reflected across a plane results in an indistinguishable structure, making it optically inactive.

What happens to a molecule when it is rotated through an angle of 360 degrees by N degrees along the axis?

How does the presence of an alternating axis of symmetry affect the optical activity of a molecule?
