Among the following, the aromatic compounds are: Choose the correct answer from the following options:
1 (A) and (B) only
2 (A), (B) and (C) only
3 (B), (C) and (D) only
4 (B) and (C) only
Explanation:
(D): Hence, $\mathrm{B}$ and $\mathrm{C}$ are aromatic compound.

Assertion: is not an aromatic compound. Reason: Presence of $4 \pi$ electrons.
1 If both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
2 If both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion.
3 If Assertion is correct but Reason is incorrect.
4 If both the Assertion and Reason are incorrect.
Explanation:
(A): Cyclopenta dienyl is not an aromatic compound because it has $4 \pi$ electrons. It does not follow huckle's rule. To follow huckle's rule. Compound should be planer and conjugated system. It must be follow $(4 n+2) \pi e^{-}$electron where $n=1,2,3 \ldots \ldots$. i.e, it should $6 \pi \mathrm{e}^{-}, 10 \pi \mathrm{e}^{-}, 14 \pi \mathrm{e}^{-}$system. So option (a) is correct both Assertion and Reason are correct and Reason is correct explanation of Assertion.

Assertion: \(+\text{ }C{{H}_{3}}-C{{H}_{2}}-C{{H}_{2}}-Cl\xrightarrow[{}]{AlC{{l}_{3}}}Product\) Reason: Due to rearrangement of primary carbocation into secondary carbocation.
1 If Assertion is correct but Reason is incorrect.
2 If both the Assertion and Reason are incorrect.
3 If both Assertion and Reason are correct and the reason is the correct explanation of Assertion.
4 If both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion.
Explanation:
(A): From the given product we can say that Both Assertion and Reason is correct and Reason is correct explanation of Assertion.

Assertion: Benzene exhibit two different bond lengths, due to $\mathrm{C}-\mathrm{C}$ single and $\mathrm{C}=\mathrm{C}$ double bonds. Reason: Actual structure of benzene is a hybrid of following two structures.
1 If both Assertion and Reason are correct and the Reason is the correct explanation of Assertion.
2 If both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion.
3 If Assertion is correct but Reason is incorrect.
4 If both the Assertion and Reason are incorrect.
Explanation:
(C): Benzene exhibit two different bond length of $\mathrm{C}-\mathrm{C}$ single and $\mathrm{C}=\mathrm{C}$ double bond due to delocalisation of $\pi$-electrons bond all bond length of $\mathrm{C}-\mathrm{C} \& \mathrm{C}=\mathrm{C}$ which $1.54 \AA$ and $1.33 \AA$ are equal and this process is called resonance So, from the explanation we can say that Assertion is correct but reason is incorrect.
