  4. DGattermann-Koch synthesis

Correct answer

B. Wacker process

Step-by-step solution

In Wacker process, when mixture of propene and air is passed through mixture of Pd and CuCl ₂ at high pressure acetone is formed. Pd + CuCl ₂ PdCl ₂+2 CuCl 4 CuCl + HCl + O ₂ 4 CuCl ₂+2 H ₂ O CH ₃ CH = CH ₂+ PdCl ₂+ H ₂ O Propane CH ₃ COCH ₃+ Pd +2 HCl
