Amongst the compounds given, the one that would from a brilliant coloured dye on treatment with NaNO2 in dil. HCl followed by addition to an alkaline solution of $$\beta$$-naphthlol is
Match each of the compounds in Column I with its characteristic reaction(s) in Column II.
Column I | Column II | ||
---|---|---|---|
(A) | $$C{H_3}C{H_2}C{H_2}CN$$ | (P) | Reduction with $$Pd - C/{H_2}$$ |
(B) | $$C{H_3}C{H_2}OCOC{H_3}$$ | (Q) | Reduction with $$SnC{l_2}/HCl$$ |
(C) | $$C{H_3} - CH = CH - C{H_2}OH$$ | (R) | Development of foul smell on treatment with chloroform and alcoholic KOH |

Statement 1 : Aniline on reaction with NaNO$$_2$$/HCl at 0$$^\circ$$C followed by coupling with $$\beta$$-naphthol gives a dark blue coloured precipitate.
Statement 2 : The colour of the compound formed in the reaction of aniline with NaNO$$_2$$/HCl at 0$$^\circ$$C followed by coupling with $$\beta$$-naphthol is due to the extended conjugation.
Match the compounds in Column I with their characteristic test(s)/reaction(s) given in Column II. Indicate your answer by darkening the appropriate bubbles of the 4 $$\times$$ 4 matrix given in the ORS.
