Structural (constitutional) isomers 2. Stereoisomers (two types) - enantiomers and diasteromers 3. Geometric isomers (also known as cis and trans isomers) what is a structural (constitutional) isomer? - CORRECT ANSWER different bonding arrangement of atoms. atoms are bonded together in a different sequence what is a stereoisomer? what are the two types of stereoisomers? - CORRECT ANSWER stereoisomers: atoms are bonded together in the same sequence, but have different 3-D arrangement in space enantiomers: non-superimposable mirror images diasteromers: stereoisomers that are not enantiomers: not superimposable and not mirror images what is a chiral atom? - CORRECT ANSWER an atom that has four different groups attached to it If a chiral atoms is in the "R" configuration, in what direction does the arc go? if a chiral atom is in the "S" configuration, in what direction does the arc go? - CORRECT ANSWER -R configuration - clockwise
