How do I invert the chirality of a structure in ChemDraw iOS?
There are two commands in the Lasso selection tool set that can be used to invert stereochemistry - Flip Horizontally and Flip Vertically. These commands perform reflections about horizontal or vertical axes respectively. To use the commands you first select the molecule, and then tap the appropriate button. If you have the display of stereochemistry labels turned on, you will note the labels will change R to S and vice versa.
