As he demonstrated, you turn the left hand 180 degrees so that the thumb is on the left side. How does that not superimpose the right hand? On the right hand, the thumb is on the left side, and so is the left hand flipped 180 degrees? Same thing for the CFCH3Br molecule.
WebJul 30, 2024 · Each chiral center in a molecule will be either R or S. As noted above, molecules with a single chiral center are chiral. Molecules with more than one chiral center are usually chiral. The exception are meso-compounds. How to: Step 1: Eliminate the atoms that cannot be chiral centers.
