Which does not represent correct method?

• A. TiCl2 + 2Mg $\longrightarrow$ Ti + 2MgCl2 : Kroll
• B. Ni(CO)4$\longrightarrow$ Ni + 4CO : Mond
• C. Ag2CO3$\frac { 1 } { 2 }$ O2 : Van Arkel
• D. ZrI4$\longrightarrow$Zr + 2I2 : Van Arkel

Answer 1

Answer: (C)

Ag2CO3$\frac { 1 } { 2 }$ O2 : Van Arkel

Answer 2

It is not called van Arkel method. Van Arkel method is used for the purification of Zr and Ti. Reaction (3) is simple thermal decomposition of Ag2CO3.
