Mention two esters produced when a recemic mixture of 2-phenyl propanoic acid is treated with (+) 2-butanol. What is the stereochemical relationship between these esters ?

Explanation

During esterification only -COOH and -OH participates. There is no effect on structure or configuration of carbon adjuscent to these groups. So when (`pm`) acid reacts with pure (+) alcohol two esters are produce which are diastereosiomers of each other,
