Describe simple chemical tests that would serve to dis tinguish between: (a) propionic acid and methyl acetate (b) n-butyryl chloride and n-butyl chloride (c) \(\mathrm{p}\) -nitrobenzamide and ethyl \(\mathrm{p}\) -nitrobenzoate (d) glyceryl tristearate and glyceryl trioleate (e) benzonitrile and nitrobenzene (f) acetic anhydride and \(\mathrm{n}\) -butyl alcohol (g) glyceryl monopalmitate and glyceryl tripalmitate (h) ammonium benzoate and benzamide (i) \(\mathrm{p}\) -bromobenzoic acid and benzoyl bromide Tell exactly what you would do and see.

To distinguish between the given compound pairs, perform simple chemical tests involving solubility, reactions, or color changes. Some examples include: (a) For propionic acid and methyl acetate, add sodium bicarbonate (NaHCO3) and observe effervescence due to CO2 release by propionic acid. (b) For n-butyryl chloride and n-butyl chloride, add silver nitrate (AgNO3) and observe the formation of white precipitate of silver chloride (AgCl) by n-butyryl chloride. (c) For p-nitrobenzamide and ethyl p-nitrobenzoate, test solubility in water. (d) For glyceryl tristearate and glyceryl trioleate, add iodine (I2) solution and observe color disappearance in case of glyceryl trioleate. (e) For benzonitrile and nitrobenzene, add concentrated hydrochloric acid (HCl) and heat the mixtures; benzonitrile will form a white precipitate of benzoic acid. (f) For acetic anhydride and n-butyl alcohol, add 2,4-dinitrophenylhydrazine (2,4-DNP) and observe yellow or orange precipitate in case of acetic anhydride. (g) For glyceryl monopalmitate and glyceryl tripalmitate, dissolve in ethanol (EtOH), add iodine solution, and observe color disappearance in case of glyceryl tripalmitate. (h) For ammonium benzoate and benzamide, heat both compounds separately and detect ammonia fumes in case of ammonium benzoate. (i) For p-bromobenzoic acid and benzoyl bromide, add water and observe hydrolysis in case of benzoyl bromide, forming a white precipitate of benzoic acid.
