Explain why the following systems are not aromatic?
Explain why the following systems are not aromatic?
✓
Answer
Due to the presence of a sp3-hybridized carbon, the system is not planar. It does contain six n-electrons but the system is not fully conjugated since all the six n-electrons do not form a single cyclic electron cloud which surrounds all the atoms of the ring. Therefore, it is not an aromatic compound.
