Problems and exercisesBonding Properties
1. Cyclohexane and cyclohexene
Do cyclohexane and cyclohexene have the same geometry?
2. Lengths and energies
Explain why the C=C bond (1.33 Å, 146 kcal/mol) is shorter and stronger than the C–C bond (1.54 Å, 83 kcal/mol), but not twice as strong.
3. Hybridization
Give the hybridization of each carbon of propene, CH2=CH–CH3, and the approximate angle around each one.
