Interpretation Introduction

Interpretation:

The aromaticity of cyclononatetraenyl anion and the dianion formed by [16] annulene is to be explained.

Concept introduction:

In accordance with the Huckel’s rule, aromatic compounds contain a planar ring and have a conjugated pi system with (4n+2)π electrons, where n=0,1,2,3,...

Aromatic compounds contain conjugated pi bonds.

All the atoms in the aromatic ring have an unhybridized p orbital.

Compounds that are planar, cyclic and having conjugated pi system, with (4n)π electrons are antiaromatic. They are highly unstable.

Consider the tetracyclic aromatic compound drawn below, with rings labeled as A, B, C, and D. (a) Which of the four rings is most reactive in electrophilic aromatic substitution? (b) Which of the four rings is least reactive in electrophilic aromatic substitution? (c) What are the major product(s) formed when this compound is treated with one equivalent of Br2?
Give reasons: (a) n-Butyl bromide has higher boiling point than f-butyl bromide. (b) Racemic mixture is optically inactive. (c) The presence of nitro group (-N02) at o/p positions increases the reactivity of haloarenes towards nucleophilic substitution reactions

(a) Draw all resonance structures for the radical that results from homolysis of the OH bond shown in red. (b) Explain why homolysis of this OH bond is preferred to homolysis of either OH bond in the other benzene ring.
