प्रश्न
How are 1 - nitropropane, 2-nitropropane and 2-methyl 2- nitropropane are distinguished from each other using nitrous acid?
उत्तर
1-Nitropropane reacts with nitrous acid to form blue-coloured nitrosonitroalkanes which dissolve in NaOH to give red solution.
2-Nitropropane reacts with nitrous acid to form blue-coloured nitrosonitroalkanes which are further insoluble in NaOH because of the absence of the alpha hydrogen atom.
2-Methyl2-nitropropane does not react with nitrous acid because it has no alpha-hydrogen atom.
