Chapter 4.13, Problem 23P

Interpretation Introduction

Interpretation:

It is to be determined whether the optically inactive form of tartaric acid studied by Pasteur could have been meso-tartatic acid.

Concept introduction:

A chiral compound contains at least one carbon which is bonded to four different atoms or groups.

A chiral compound does not have any elements of symmetry.

Molecules containing two identical chiral centers can be achiral.

A molecule containing two or more equivalent chiral centers and an internal plane of symmetry is called a meso isomer or compound.

Meso compounds are optically inactive.
