1.	Which one of the following is the correct statement
Answer» Archiral molecules are superimposable Alanine is optically inactive amino acid Glycine is optically ACTIVE amino acid Racemic lactic acid is optically active Solution :Achiral molecules are superimposable. Racemic mixtures are optically inactive due to EXTERNAL compensation. If during a reaction, no bond to the STEREO centre is broken, the product will have the same general configuration of atoms or GROUP i.e., retention of configuration as Even though sign of optical ROTATION has changed but configuration is retended.
