Decide how many of the molecules below can also be both cis and trans ring fused by building models:
- A hexagon fused to a pentagon- An octagon fused to a square- Two squares fused together- Two hexagons fused together, and one of the hexagons has a circle inside of it (resonance structure)
A. None of these can be both cis and trans ring fusedB. One of these can be both cis and trans ring fusedC. Two of these can be both cis and trans ring fusedD. Three of these can be both cis and trans ring fusedE. All of these can be both cis and trans ring fused
