Identify products \(P_1\) and \(P_2\) formed when Benzonitrile undergoes the following reactions:
(I) Benzonitrile \(\xrightarrow[(ii)\ H_3O^+]{(i)\ SnCl_2/HCl/ether} [X]\) (II) \([X] \xrightarrow[(ii)\ H_3O^+]{(i)\ HCN} [P_1]\) (III) \(2\) moles of \(X + 50% NaOH \rightarrow [P_2] +\) Salt
A compound \(C_3H_5N\) undergoes reduction to form a primary amine. The amine gives compounds [B] and [C] in the following reactions. Identify [B] and [C].
Two statements, one Assertion and the other Reason are given. Identify the correct option
Assertion : Primary and secondary amides on treatment with \( Br_2 \) and alcoholic \( NaOH \) yield primary and secondary amines respectively and the reaction involves stepping down the series.
Reason : The reaction occurs due to the migration of alkyl group from Carbonyl carbon atom to the Nitrogen atom with elimination of carbonyl group as the carbonate salt.
An optically active compound [X] (Molecular formula \( C_8H_{11}N \)) reacts with \( CHCl_3/ \) Ethanolic KOH on heating to form an isocyanide. On reaction with \( NaNO_2/HCl \), it yields an alcohol with liberation of \( N_2 \). Identify the compound [X].
An organic compound A (C\(_5\)H\(_9\)N) upon reaction with Na/Hg/C\(_2\)H\(_5\)OH gives compound B. B reacts with NaNO\(_2\)/HCl at 274 K to form C with quantitative liberation of N\(_2\) gas. B also reacts with Hinsberg's reagent to form a compound which is soluble in alkali. Identify compound B.
