Which of the following is not the correct reaction of aryl diazonium salts?

Options

A. `C_6 H_5 N_2^+ Cl^- + Cu_2 Cl_2 to C_6 H_5 Cl`
B. `C_6 H_5 N_2^+ Cl^- + HBF_4 overset("Heat")to C_6 H_5 F`
C. `C_6 H_5 N_2^+ Cl^- + H_3 PO_2 to C_6 H_5 PO_4`
D. `C_6 H_5 N_2^+ Cl^- + SnCl_2//HCl to C_6 H_5 NHNH_2`

Answer

C

Explanation

`H_3 PO_2` reduces diazonium salt to hydrocarbon.
