Examine the drawings of tartaric acid shown below. Note that tartaric acid has two chiral centres so we can draw 4 compounds (labelled $1?4$ ) to represent 4 possible stereoisomers. Drawings of different optical isomers of tartaric acid a. Determine the configurations of the chiral centres for each isomer of tartaric acid. Isomer 1 : Isomer 2 : Isomer 3 : Isomer 4: b. What do you call an isomer with more than 1 stereocentre but achiral, like isomer 3 , and possess a plane of symmetry? c. There are less optical isomers than the maximum number expected for tartaric acid explain why this occurs. Consider the molecules given below and answer the question following: Would the following be optically active? Briefly explain. a. A pure solution of $B$ b. An equimolar mixture of $A$ and $B$ c. A $25\%?75\%$ mixture of $A$ and $C$ Page 8 of 1
