Interpretation Introduction

Interpretation: The chiral molecule/s needs to be identified from the three related angiotensin converting enzyme inhibitors. The number of stereoisomers possible needs to be identified for each chiral molecule. The three structures need to be compared with captopril and similarity among four drugs needs to be explained.

Concept Introduction:

A molecule is said to be chiral if it is non-superimposable with its mirror image. For example, left and right hands. These two non-superimposable mirror images of chiral molecules are known as enantiomers.
