Concept explainers
(a)
Interpretation:
Whether the given compound is optically active or not needs to be determined.
Concept Introduction:
The ball-stick model is a method of representation of molecules to demonstrate the three-dimensional position of atoms and the bonds. The atoms are represented by different colored spheres, while bonds are represented by rods connecting the spheres. Chiral or optically active molecules can rotate plane-polarized light either clockwise or counterclockwise. If plane-polarized light is rotated clockwise then it is known as dextrorotatory and for counterclockwise rotation, it is known as levorotatory.
