front 1 isomer | back 1 each of two or more compounds with the same formula but a different arrangement of atoms in the molecule and different properties. |
front 2 enantiomer | back 2 mirror image molecules, same molecular formula |
front 3 structural isomer | back 3 one of two or more compounds that contain the same number and kinds of atoms but that differ significantly in their geometric arrangement |
front 4 cis-trans isomer | back 4 geometric isomers, where the functional group is placed differently with regards to the double bond. cis isomer has molecules on one side of the double bond. A trans isomer has molecules on the other side of the double bond |
