Make a model of a 1 carbon molecule that has an ASYMMETRIC CARBON. Make a model of a ENANTIOMER isomer for this molecule. Show your neighbor. Are these enantiomers? DRAW a picture of your isomers in your BILL. Give an example of enantiomer isomers with different properties

Does this molecule have an asymmetric carbon Does this molecule have an asymmetric carbon? If so, which one is asymmetric? Would you expect this molecule to exist as enantiomer isomers?
