Q. 6

Which of the following reagents would not be a good choice for reducing an aryl nitro compound to an amine?
A. H2 (excess)/Pt

B. LiAlH4 in ether

C. Fe and HCl

D. Sn and HCl

Answer :


• When nitrobenzene reacts with LiAlH4 in ether medium, it does not transform itself to amine, instead another product is formed which is azobenzene . So this reagent will not be a good choice for converting of nitrobenzene to amine.


Other 3 given reagents (i) H2 (excess)/Pt (iii) Fe and HCl and (iv) Sn and HCl are actually efficient choice for the conversion.
