Correct Answer: C
Solution :
[A] \[1{}^\circ \] amines give a bad smelling compound, called carbylamine, with alcoholic KOH and \[CHC{{l}_{3}}.\]The reaction is called carbylamines reaction. \[C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}C{{H}_{2}}N{{H}_{2}}\xrightarrow[{}]{CHC{{l}_{3}}+alc\,KOH}\]\[\underset{\text{bad}\,\text{smelling}}{\mathop{\text{C}{{\text{H}}_{\text{3}}}{{\text{(C}{{\text{H}}_{\text{2}}}\text{)}}_{\text{3}}}\text{NC}}}\,\] [B] Terminal alkynes like \[C{{H}_{3}}C\equiv CH\] give white precipitate with ammonia cal\[AgN{{O}_{3}}.\] \[C{{H}_{3}}C\equiv CH+AgN{{O}_{3}}+N{{H}_{4}}OH\xrightarrow[{}]{{}}\]\[\underset{\text{white}\,\text{ppt}}{\mathop{C{{H}_{3}}C\equiv CAg}}\,\] [C] Ester \[(C{{H}_{3}}C{{H}_{2}}COOC{{H}_{3}})\]undergoes alkaline hydrolysis. \[C{{H}_{3}}C{{H}_{2}}COOC{{H}_{3}}+NaOH\xrightarrow[{}]{{}}\]\[C{{H}_{3}}C{{H}_{2}}COONa+C{{H}_{3}}OH\] [D]\[2{}^\circ \] alcohols (the alcohols that have \[C{{H}_{3}}CHOH-\]group) give cloudiness with Lucas reagent (anhy \[\text{ZnC}{{\text{l}}_{\text{2}}}\text{+}\] + cone HCl): within 5 minutes.You need to login to perform this action.
