Identify the product $X$ in the following reaction:
$\text{Benzene} + Cl_{2(\text{excess})} \xrightarrow{AlCl_3, \Delta} X$

What is the product of the following reaction?
$C_6H_6 + CH_2=CH_2 \xrightarrow{HCl, AlCl_3} \text{Product}$

Which compound is formed when benzene is heated with chlorine in the presence of sunlight?

Given below are two statements. One is labelled as Assertion $A$ and the other is labelled as Reason $R$.
Assertion $A$: $[6]-$Annulene,$[8]-$Annulene and cis$-10-$Annulene are respectively aromatic,non-aromatic and non-aromatic.
Reason $R$: Planarity is one of the requirements of aromatic systems.
In the light of the above statements,choose the most appropriate answer from the options given below.

Identify the end product $(Z)$ in the sequence of the following reactions:
$C_2H_4Br_2$ $\xrightarrow[(ii) NaNH_2]{(i) Alc. KOH} X$ $\xrightarrow[873 \ K]{\text{Red hot Fe tube}} Y$ $\xrightarrow[\text{Anhy } AlCl_3, \Delta]{CH_3COCl} Z$

$C_6H_6$ $\xrightarrow{CH_3COCl/AlCl_3} A$ $\xrightarrow{Zn-Hg/HCl} B$
The end product in the above sequence is:
