WebA Fischer projection is the most useful projection for discovering enantiomers. Compare the 2‐chlorobutane enantiomer structures in this diagram. Rotating structure ( b) 180° in the plane of the paper, the only allowable rotation, does not lead to a form that is superimposable on structure ( a). Rotations of less than or more than 180° are ...
