QJEEM23Ch3c98: JEE Main 2023 Chemistry - Class 11 JEEM23Ch3c98 Solution: Given below are two statements : Statement I : Tropolone is an…

Let's analyze the structure of tropolone to evaluate the given statements.

1. Statement I: "Tropolone is an aromatic compound and has $8 \pi$ electrons."

Tropolone is a seven-membered ring compound with an oxygen atom attached to it through a double bond, creating a carbonyl group (C=O). To determine if it is aromatic, we should check if it meets Hückel's rule for aromaticity, which states that a molecule is aromatic if it is cyclic, planar, and has a $4n + 2$ $\pi$ electrons (where n is a non-negative integer).

Upon examining the structure of tropolone:

According to the table, tropolone has a total of 8 $\pi$ electrons. Since 8 does not satisfy the $4n + 2$ rule (where n would be 1 or 2, leading to 6 or 10 $\pi$ electrons), tropolone does not qualify as aromatic. Therefore, Statement I is false.

2. Statement II: " $\pi$ electrons of > \mathrm{C}=\mathrm{O} group in tropolone is involved in aromaticity."

As established, tropolone does not meet the criteria for aromaticity. Additionally, the $\pi$ electrons of the carbonyl group indeed contribute to the total count of $\pi$ electrons in the ring system, but since tropolone isn't aromatic, Statement II is false.

Given the analysis, the correct answer is:

Option B: Both Statement I and Statement II are false
