7-bromo-1,3,5-cycloheptatriene exists as ionic species in aqueous solution while 5-bromo-1,3-cyclopentadiene doesn't ionise even in presence of `Ag^(+)(aq)`, Explain.

Explanation

To explain why 7-bromo-1,3,5-cycloheptatriene exists as ionic species in aqueous solution while 5-bromo-1,3-cyclopentadiene does not ionize even in the presence of Ag⁺(aq), we can follow these steps:

### Step 1: Analyze the Structure of 7-bromo-1,3,5-cycloheptatriene
- The structure of 7-bromo-1,3,5-cycloheptatriene can be drawn with a bromo group at the 7th position and double bonds at the 1st, 3rd, and 5th positions.
- This compound has a total of 6 π electrons from the three double bonds.

### Step 2: Evaluate the Ionization of 7-bromo-1,3,5-cycloheptatriene
- When the bromine atom (Br) is removed, it leaves behind a carbocation (positively charged carbon).
