Consider the above sequence of reactions. The number of bromine atom$(s)$ in the final product $(P)$ will be:

The final product $A$, formed in the following multistep reaction sequence is:

Consider the following sequence of reactions to produce major product $(A)$. Molar mass of product $(A)$ is $........... \ g \ mol^{-1}$. (Given molar mass in $g \ mol^{-1}$ of $C : 12, H : 1, O : 16, Br : 80, N : 14, P : 31$)

Consider the following sequence of reactions:
Chlorobenzene $\xrightarrow[ii) CO_2, H_3O^{+}]{i) Mg, \text{dry ether}} \text{Benzoic acid}$ $\xrightarrow{NH_3, \Delta} \text{Benzamide (A)}$ $\xrightarrow{Br_2, NaOH} \text{Aniline (B)}$
$11.25 \ mg$ of chlorobenzene will produce $.......... \times 10^{-1} \ mg$ of product $B$.
(Consider the reactions result in complete conversion.)
[Given molar mass of $C, H, O, N$ and $Cl$ as $12, 1, 16, 14$ and $35.5 \ g \ mol^{-1}$ respectively]

Match the Compounds (List-$I$) with the appropriate Catalyst/Reagents (List-$II$) for their reduction or conversion into corresponding amines.

List-$I$ (Compounds)	List-$II$ (Catalyst/Reagents)
$A$. $R-CONH_2$	$I$. $NaOH$ (aqueous)
$B$. $C_6H_5NO_2$	$II$. $H_2 / Ni$
$C$. $R-C \equiv N$	$III$. $LiAlH_4, H_2O$
$D$. $N$-alkylphthalimide	$IV$. $Sn,HCl$
