Newman projector The eclipsed for has the most torsion strain Torsional: repulsion among electrons in different groups as they pass each other during bond rotation Steric: repulsion between electrons in different groups, but cannot be lessened by bond rotation Angle: bond angles differ from ideal geometry With more CC bonds, there is less strain such as cyclohexane. All CH bonds are staggered Twist boat is at the local energy minimum the diagram in chairchair interconversion of cyclohexane Compound name Asymmetric carbon Stereo center 3 groups present on given carbon All 4 groups must be different to be asymmetric How to draw enantiomers Perspective formulas 2 single lines: in plane Dashed line: back Solid wedge: front Fischer Projections Horizontal line: front Vertical line: back Intersection: asymmetric carbon Types of Isomers Identical compound can be determined if two compounds that are both S or R configure Constitutional isomer Stereoisomers Functional Positional isomers Diastereomers Enantomers Group (includes cis/trans Ex: CH C3 OH 2 Ex: CH C3 CH2CH C2 2 isomers) CH O3H 3 C3 CH2H 3 Fischer Molecules with multiple asymmetric carbons 2 possible stereoisomers n= # of asymmetric carbons Diastereomers Fischer projection, longest chain on vertical line, are in eclipsed conformations (2S, 3S) 3 bromobutan2ol 2 asymmetric Centers: 3 stereoisomers (a meso compound and a pair of enantiomers) Eisomer (Epposite) Zisomer (Zame)
