Question

Which of the following is a true statement?

A. All achiral molecules are meso.
b. All chiral molecules possess a plane of symmetry.
c. All molecules which posses a single asymmetric center of the S configuration are levorotatory .
D. A mixture of achiral compounds will be optically inactive.
E. All molecules which possess 2 or more chirality centers will be chiral.

Answer 1

An archival molecule has a non super imposable mirror image. And meso has a plane symmetry through the center carbon. So some achiral molecules are meso but all are not meso Hence, the option is false All chiral molecules have no plane of symmetry. Some symmetry chiral are form without plane of Hence, the option is false Some molecules which have a single asymmetry center of S configuration are levorotatory or may be dextrorotatory Hence, the option is false A mixture of achiral compound will be inactive if it rotates polarized light Hence, the option is true A molecules that posses two or more stereogenic centers are known achiral molecules. It is not called chiral molecules Hence, the option is false
