What will be the final product in the given reaction?

In the reaction shown below,the structural formula of $(A)$,$X$ and $Y$ respectively are:
$C_7H_7N_2OCl + C_2H_5OH \rightarrow \text{Anisole} + N_2 + X + Y$

Complete the following reactions:
$(1)$ $1$-Chloropropane $\xrightarrow[{KOH}]{{\text{ethanol}}} (B)$ $\xrightarrow[{CCl_4}]{{Br_2}} (C)$
$(2)$ Ethane $\xrightarrow[{hv}]{{Cl_2}} (B)$ $\xrightarrow[{Na, \text{ether}}]{} (C)$

Match the List-$I$ with List-$II$:

List-$I$ Name reaction	List-$II$ Product obtainable
$A.$ Swarts reaction	$I.$ Ethyl benzene
