The reaction of an aromatic halogen compound with an alkyl halide in the presence of sodium and ether is called:

Which of the following reactions is called the Wurtz-Fittig reaction?

The major product obtained in the following reaction is: Chlorobenzene + chlorine $\xrightarrow[FeCl_3]{\text{Anhydrous}}$ product (Major)

How will you convert benzene into:
$(i)$ $p-$nitrobromobenzene
(ii) $m-$nitrochlorobenzene

Aryl halides are less reactive towards nucleophilic substitution reactions compared to alkyl halides because of:

The reaction of compound $P$ with $CH_3MgBr$ (excess) in $(C_2H_5)_2O$ followed by addition of $H_2O$ gives $Q$. The compound $Q$ on treatment with $H_2SO_4$ at $0^{\circ}C$ gives $R$. The reaction of $R$ with $CH_3COCl$ in the presence of anhydrous $AlCl_3$ in $CH_2Cl_2$ followed by treatment with $H_2O$ produces compound $S$ [$Et$ in compound $P$ is ethyl group].
$(1)$ The product $S$ is
$(2)$ The reactions,$Q$ to $R$ and $R$ to $S$,are

$A$. Dehydration and Friedel-Crafts acylation	$B$. Aromatic sulfonation and Friedel-Crafts acylation
$C$. Friedel-Crafts alkylation,dehydration and Friedel-Crafts acylation	$D$. Friedel-Crafts alkylation and Friedel-Crafts acylation

Given the answer question $(1)$ and $(2)$
