What is the product of the reaction?

Identify the major product formed from the sequence of reactions given below:
$C_6H_5NH_2$ $\xrightarrow[(ii) Cu_2Cl_2]{(i) NaNO_2/HCl, 273 K}$ $\xrightarrow{(iii) Na/dry ether} \text{Product}$

Match the following reactions in List-$I$ with their major products in List-$II$.

List-$I$ (Reaction)	List-$II$ (Major product)
$A. \ CH_3CH=CH_2 \xrightarrow{HI}$	$I. \ 1\text{-bromo-}2\text{-phenylethane}$
$B. \ C_6H_5CH_2CH_3 \xrightarrow{Br_2/\Delta}$	$II. \ 1\text{-iodopropane}$
$C. \ C_6H_5CH=CH_2 \xrightarrow{HBr}$	$III. \ 2\text{-iodopropane}$
	$IV. \ 1\text{-bromo-}1\text{-phenylethane}$

The correct match is:

Assertion : Alkylbenzene is not prepared by Friedel-Crafts alkylation of benzene.
Reason : Alkyl halides are less reactive than acyl halides.

Consider the following $E_1/S_N1$ reaction. The missing product$(s)$ is(are):

Consider the following sequence of reactions:
Nitrobenzene $\xrightarrow[(ii) NaNO_2, HCl, 0^{\circ}C]{(i) Sn + HCl} \text{Benzenediazonium chloride}$ $\xrightarrow{(iii) Cu_2Cl_2} \text{Chlorobenzene}$ $\xrightarrow{(iv) Na, \text{Ether}} A$
Molar mass of the product formed $(A)$ is $.............. \ g \ mol^{-1}$.
