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