Transition metals and their coordination compounds function as vital industrial catalysts due to the — d and f Block Elements Chemistry Question

💡 Solution & Explanation

Transition metals are ubiquitous catalysts. The Deacon's process, which involves the oxidation of hydrogen chloride ($HCl$) gas by atmospheric oxygen to produce chlorine gas ($Cl_2$), is specifically catalyzed by Copper(II) chloride ($CuCl_2$). In contrast, the Wacker process uses $PdCl_2$, the Contact process uses $V_2O_5$, and Ziegler-Natta uses $TiCl_4$.
