Interpretation:
The stable configuration of [16]annulene is to be drawn and whether it is
Concept introduction:
The monocyclic hydrocarbons with alternate single and double bonds are called annulenes. They are commonly named as [n] annulenes, where ‘n’ represents the number of carbon atoms in the ring. The stability of [n] annulenes depends on their angle strain between alternate single and double carbon-carbon bonds. To avoid this angle strain in [n] annulenes, a carbon-carbon double bond arranges in alternate cis and trans fashion.
The rule for aromaticity or antiaromaticity applies only if the system is planar, cyclic and has an overlapping p-orbital which could contribute to the conjugation.
1) Aromatic if the number of electrons in that
2) Antiaromatic if the number of electrons in that
3) All other species are considered nonaromatic.
In other words, if a species contains an odd number of pi electrons, then it is said to be aromatic. If it contains an even number of pi electrons, then it is anti-aromatic.
