Match the compounds given in List I with their characteristic reactions given in List II. Select the correct option.                  [AIPMT (M) 2010]

List I (Compounds) List II (Reactions) A.\[\text{C}{{\text{H}}_{\text{3}}}\text{C}{{\text{H}}_{\text{2}}}\text{C}{{\text{H}}_{\text{2}}}\]\[\text{C}{{\text{H}}_{\text{2}}}\text{N}{{\text{H}}_{\text{2}}}\] B.\[\text{C}{{\text{H}}_{3}}\text{C}\equiv \text{CH}\] C. \[\text{C}{{\text{H}}_{\text{3}}}\text{C}{{\text{H}}_{\text{2}}}\text{COOC}{{\text{H}}_{\text{3}}}\] D.\[\text{C}{{\text{H}}_{\text{3}}}\text{CH(OH)C}{{\text{H}}_{\text{3}}}\] 1. Alkaline hydrolysis 2. With KOH (alcohol) And \[\text{CHC}{{\text{l}}_{\text{3}}}\]produces bad smell 3. Gives white ppt with ammoniacal \[\text{AgN}{{\text{O}}_{\text{3}}}\] 4. With Lucas reagent cloudiness appears after 5 min

A) A-2, B-1, C-4, D-3

B) A-3, B-2, C-1, D-4

C) A-2, B-3, C-1, D-4

D) A-4, B-2, C-3, D-1

Correct Answer: C

Solution :

[c] 1° amines give a bad smelling compound, called carbylamine, with alcoholic KOH and The reaction is called carbylamines reaction.

Terminal alkynes like  give white precipitate with ammonia cal

Ester

undergoes alkaline hydrolysis.

2° alcohols (the alcohols that have group) give cloudiness with Lucas reagent (anhy  + cone HCl): within 5 minutes.
