Answer 1

1 The given unknown compound is insoluble in water, 5% HC, conc. H₂SO4 It may be alkano con alkyl hal.de Test for alkyl halide - silver Nitonitie (AgNO₃) + alcohol. If it is negative, the compound is alkane 2) The given unknown nown compound is soluble in wator (to), compound is sok 5% NaHCO₂, does not evolve bubbles. The compound may be carbohydrate | anide Tast få carbohydrate molisch, Tollens, Fehling Teste. If it is positive then the compound is cooho hydrate, If it is negative - amide 3) The given unknown compound may be alkone, alcohol, aldakyake Ketone as it soluble in Conc. He so and insoluble im H₂O 5% NaOH, St. Hel. but the above compound does not give Tollens, Kimmo Tost i e. the compound cannot be an alkene con aldehyde. in the compound may be ketone. - Test for Ketone: Schift's Test, sodium nitro poubide, 3 The given unknown compound may be phenolic as it is insoluble im H₂o and 5%. NaHCO, soluble i'm 5% Naoh. Test for phenol a neutral Fecla Pthalic anhydride, Azodye Test
