Chapter 8 Notes – Isomers and Stereochemistry Isomers: compounds that have the same molecular formula but are not identical Constitutional isomers: differ in the way that their atoms are connected Stereoisomers: differ in the way their atoms are arranged in space; cis-trans isomers and isomers that contain asymmetric centers 8.1 – Cis-Trans Isomers - Result from restricted rotation caused by either a double bond or a cyclic structure - Cis – same side of the double bond - Trans – opposite side of the double bond 8.2 – Chirality - Chiral: an object with right-handed and left-handed form - Have non-superimposable mirror images, which means the mirror image is not the same as itself - Achiral: objects that are not chiral, such as a chair, and that have superimposable mirror images 8.3 – Asymmetric Centers - A molecule with one asymmetric center is chiral - An asymmetric center is an atom that is bonded to four different groups 8.4 – Isomers with One Asymmetric Center - A compound with one asymmetric center can exist as two different stereoisomers
