PCAT Chemical Processes – Chlorines Molecule

- PCAT Question of the Day
A: Enantiomers are mirror images of each other. The mirror image of a cis arrangement would still be cis, thus this is incorrect.
C: Tautomers are a form of constitutional isomer in which the bonding between the atoms is changed. The molecules depicted have the same bonding arrangment, so they are not tautomers. Also, by far the most common tautomer on the MCAT is the ketone / enol tautomer, which this is not.
D: Conformers can be freely interconverted by rotation around a single bond, with no bond-breaking. Here, there’s no way to convert between cis and trans without breaking bonds.
