Answer 1

Reaction with Ninogen compound (OND) (a) Benzaldenyde = Positive (b) methyl ethyl Kelone - Positive (c) Uknoum = Kerone or aldehyde - Part (11) Chromic Acid Test- oxidation with Jones Reagent Positiu enly aldehyde and Primary alienots Gius positive Negathul Test with Jeni's (C) methyl ethye ketone Reagent (Q) Pro pienaldehyde (b) Acetone Negatiul U known Aldehyde y Positive and lone Negattee → paut (111) Tollen's Test- silver miror Test for aldehydes vom op only aliny ces give positive Tollend Test lie Silver mirror appears in lase og aldehydes a) Propional deny de - Positive () methyl ethye ketone = b) Benzaldeny de - Positive Negative d) Unknown - f + ue Then may be aldehyde

Part IV Jodoform Test for methyl Kerones (a) methyl ethyl Ketone = CH3 - 8 - CaH5 = (Positive) (b) Unknown Ia | NaOH f Your Test is possilue with a Then compound may be methyl Ketone
