7. The conjugated diene, 1,3-cyclohexadiene, has four \( \pi \)-molecular orbitals. In order of increasing energy these are: \( \pi_{1}, \pi_{2}, \pi_{3} \) and \( \pi_{4} \). Which of these is the HOMO of the electronic ground state? A) \( \pi_{1} \) B) \( \pi_{2} \) C) \( \pi_{3} \) D) \( \pi_{4} \)
