The bond lengths of carbon–carbon, carbon–nitrogen, carbon– oxygen, and nitrogen–nitrogen single, double, and triple bonds are listed in Table 8.5. Plot bond enthalpy (Table 8.4) versus bond length for these bonds (as in Figure 8.17).What do you conclude about the relationship between bond length and bond enthalpy? What do you conclude about the relative strengths of bonds?
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 H
