👉 The term "isocyclic" refers to a cyclic structure in which atoms share the same number of electrons, typically 8. This means that when two such structures are combined, they form a complete cycle, which is not possible with non-isocyclic structures. Isocycles are often found in organic molecules where the carbon atom can be shared between two or more identical orbitals to form an octet, as in nitrogen (N) and oxygen (O).
