1.Which of the following is not a requirement of aromaticity? Group of answer choices The structure must be planar or near planar. each atom in the ring must have an unhybridized p orbital The p-orbitals must overlap continuously in a ring. Structure must be acyclic Delocalization of the pi electrons over the ring must lower the energy of the system.
