Question

The reduction of nitro compounds is most preferred in the
presence of

Pd/H, in ethanol

Sn + HCI

finely divided Ni

iron scrap and HCI .​

Answer 1

Answer:

the reduction of nitro compounds is most preferred in the presence of

Sn+HCL

Answer 2

The reduction of nitro compounds is most preferred in the presence of Sn + HCl, because of the following reasons:-

• Nitro compounds react with Ethanol in presence of Palladium and hydrogen to stabilize some unstable reaction intermediate. So, option 'A' is incorrect.
• Nitro compounds are effectively converted into amines with good yield.
• The use of catalysts such as Sn + HCl yields the formation of pure amines.
• Products form after the reaction include Gaseous SnCl2 and H2 gas which escape and give pure amines at the end. So, option 'B' is correct.
• Nitro compounds on reaction with finely divided Nickel or Iron reduces to amines but don't give a good yield. So, option 'C' and 'D' are also incorrect.

Hence, The reduction of nitro compounds is most preferred in the presence of Sn + HCl. and option 'B' is correct.
