Optical isomerism
This molecule has an asymmetric carbon (4 different groups bonded to the same atom) — it exists in two non-superimposable mirror-image forms called enantiomers. Use the Mirror button in the controls to switch between R and S.
R · RectusGroup priorities rotate clockwise (with the lowest-priority group pointing away).
S · SinisterGroup priorities rotate counter-clockwise. Rotates polarized light in the opposite direction to R.
