Which of the following reagents would not be a good choice for reducing an aryl nitro compound to an amine?

पर्याय

  • \[\ce{H2 (excess)/Pt}\]

  • \[\ce{LiAlH4}\] in ether

  • \[\ce{Fe}\] and \[\ce{HCl}\]

  • \[\ce{Sn}\] and \[\ce{HCl}\]

MCQ

उत्तर

\[\ce{LiAlH4}\] in ether

Explanation:

Lithium aluminium hydride in either is a strong reducing agent that donated its \[\ce{H-}\] hydride ion to any \[\ce{C = O}\] containing a functional group. In addition to \[\ce{LiAlH}\], to aryl nitro compounds, no reaction will be observed, the desired products of amines will not be produced, rather it will form diazobenzene products.

\[\ce{2C4H5NO ->[LiAlH4/ether] C6H5N = N - C6H5}\]
