In the reaction, A is

In the reaction, In the reaction, A is
AA is

Options

  1. AHgSO4/H2SO4\mathrm{HgSO}_4 / \mathrm{H}_2 \mathrm{SO}_4
  2. BCu2Cl2\mathrm{Cu}_2 \mathrm{Cl}_2
  3. CH3PO2\mathrm{H}_3 \mathrm{PO}_2 and H2O\mathrm{H}_2 \mathrm{O}
  4. DH+/H2O\mathrm{H}^{+} / \mathrm{H}_2 \mathrm{O}

Correct answer

C. H3PO2\mathrm{H}_3 \mathrm{PO}_2 and H2O\mathrm{H}_2 \mathrm{O}

Step-by-step solution

When diazonium salt is treated with H3PO2\mathrm{H}_3 \mathrm{PO}_2 followed by hydrolysis, it diazonium group is replaced by −H-\mathrm{H} resulting to the formation of hydrocarbon. Thus, AA must be H3PO2/H2O\mathrm{H}_3 \mathrm{PO}_2 / \mathrm{H}_2 \mathrm{O}. In the reaction, A is
