7-bromo-1,3,5-cycloheptatriene exists as ionic species in aqueous solution while 5-bromo-1,3-cyclopentadiene does not ionise even in presence of AgNO3(aq) because
- a)C—Br bond has partial double bond character in 5-bromo-1,3-cyclopentadiene
- b)7-bromo-1,3,5-cyclopheptatriene ionises to form an aromatic anion while 5-bromo-1,3-cyclopentadiene ionises to form an anti-aromatic cation
- c)7-bromo-1,3,5-cycloheptatriene ionises into an aromatic cation while 5-bromo-1,3 cyclopentadiene ionises into a highly unstable anti-aromatic cation
- d)Both ionises to form anions but one form aromatic while other form anti-aromatic anion
Correct answer is option 'C'. Can you explain this answer?

The correct answer is Option C.
The C-Br bond in the case of 7-bromo-1, 3, 5-cycloheptatriene is broken easily because the intermediate carbocation formed is very stable (aromatic as it contains (4n + 2)π e- ie, follows Huckle rule) while it does not break easily in the case of S-bromo-1, 3-cyclopentadiene because carbocation formed here is highly unstable as it is anti aromatic ie, does not follow Huckel rule. (It contains 4π electrons).

Explanation:
7-bromo-1,3,5-cycloheptatriene:
- 7-bromo-1,3,5-cycloheptatriene is an aromatic compound due to the presence of a continuous conjugated system of π electrons in the ring.
- When it ionizes in aqueous solution, it forms an aromatic cation which is relatively stable.
5-bromo-1,3-cyclopentadiene:
- 5-bromo-1,3-cyclopentadiene, on the other hand, does not form an aromatic system when ionized in aqueous solution.
- The ionized form would result in a highly unstable anti-aromatic cation due to the presence of 4n π electrons in the cyclic system.
Comparison:
- The key difference lies in the aromaticity of the resulting ions upon ionization.
- 7-bromo-1,3,5-cycloheptatriene forms an aromatic cation, making it relatively stable in aqueous solution.
- 5-bromo-1,3-cyclopentadiene, however, forms a highly unstable anti-aromatic cation, preventing it from ionizing in the same way as the former compound.
