Question

Nitro compounds can be reduced with active metals such as Fe, Sn, Zn etc. Which of the following is true statement?

• A. The reduction with fe/ HCl is preferred.
• B. The reduction with Sn/ HCl is preferred.
• C. The reduction with Zn / HCl is preferred.
• D. The reduction with Sn/HCl and Zn/ HCl is preferred.

Answer 1

The correct option is A The reduction with fe/ HCl is preferred.

The reduction with fe/ HCl is preferred. $FeC{l}_2$ formed gets hydrolysed to release HCl. Hence, only a small amount of HCl is needed to initiate the reaction.
