Identify the product obtained when nitro alkanes are treated with Sn / HCl.

Options

  1. AR-NH ₂
  2. BR ₂ NH
  3. CR ₃ N
  4. DR ₄ N ^+ X ^-

Correct answer

A. R-NH ₂

Step-by-step solution

Nitro alkanes are reduced to primary amines when treated with a mixture of tin and hydrochloric acid (Sn/HCl). The reaction involves the reduction of the nitro group ( - NO ₂ ) to an amino group ( - NH ₂ ). R-NO ₂ + 6[ H ] Sn/HCl R-NH ₂ + 2 H ₂ O Thus, the product obtained is a primary amine, R-NH ₂ . Answer: R-NH ₂
