(B) $1$. Ethyl chloride $(C_2H_5Cl)$ on reduction with $Zn-Cu$ couple and alcohol gives ethane $(C_2H_6)$. This is correct.$2$. The reaction of methyl magnesium bromide $(CH_3MgBr)$ with acetone $(CH_3COCH_3)$ gives tert-butanol ($2$-methylpropan-$2$-ol),not butanol-$2$. Thus,statement $B$ is wrong.$3$. Alkyl halides follow the reactivity sequence $R-I > R-Br > R-Cl > R-F$ due to the decreasing bond dissociation energy of the $C-X$ bond. This is correct.$4$. $C_2H_4Cl_2$ exists as two isomers: $1,1$-dichloroethane and $1,2$-dichloroethane. This is correct.

$A$. $ROH + SOCl_2 \rightarrow$	$P$. Darzen process
$B$. $RX (Cl, Br) + NaI \rightarrow$	$Q$. Finkelstein reaction
$C$. $RX (Cl, Br) + AgF \rightarrow$	$R$. Swarts reaction
$D$. $ArX + RX + Na \rightarrow$	$S$. Wurtz-Fittig reaction
