In the reaction, A is

Options

  1. AHgSO ₄ / H ₂ SO ₄
  2. BCu ₂ Cl ₂
  3. CH ₃ PO ₂ and H ₂ O
  4. DH ⁺ / H ₂ O

Correct answer

C. H ₃ PO ₂ and H ₂ O

Step-by-step solution

When diazonium salt is treated with H ₃ PO ₂ followed by hydrolysis, it diazonium group is replaced by - H resulting to the formation of hydrocarbon. Thus, A must be H ₃ PO ₂ / H ₂ O .
