From a kaplan practice exam:
- Molecular orbitals in hydrocarbons are formed between the 1s atomic orbital of hydrogen and the sp, sp2, or sp3 hybrid atomic orbitals of carbon. Which choice correctly lists the energy level of the C-H bonds, from lowest to highest?
- C6H6, HC≡CH, CH4
- H2C=CH2, CH4, C6H6
- C6H6, CH4, H2C=CH2
- HC≡CH, C6H6, CH4
- C6H6, HC≡CH, CH4
