Heating chlorobenzene with chloral in the presence of concentrated $H_2SO_4$ yields which of the following products?

Identify compounds $A$ and $E$ in the following reaction sequence.

$Benzyne$ intermediate is not observed in :

Which of the following reasons support that aryl halides are less reactive than alkyl halides towards nucleophilic substitution reactions?
$a)$ The formation of more stable arenium ion
$b)$ Partial double bond character of $C-X$ bond
$c)$ Longer $C-X$ bond
$d)$ $sp^2$ carbon bonded to $X$ is more electronegative

$\text{Benzene} + Cl_2$ $\xrightarrow{FeCl_3} X$ $\xrightarrow{R-X, \text{ Na/dry ether }} Y$
Conversion of $X$ to $Y$ is an example of:

Assertion : Chloral reacts with chlorobenzene to form $DDT$.
Reason : It is an electrophilic substitution reaction.
