Transition metals and their derived compounds are critically utilized globally as highly efficient i — d and f Block Elements Chemistry Question

💡 Solution & Explanation

The Wacker process (oxidation of ethylene to acetaldehyde) rigidly utilizes $PdCl_2$ as the active catalyst. The Ziegler-Natta catalyst (for polymerizing alkenes) is universally a mixture of $TiCl_4$ and an aluminum alkyl. The Contact process (manufacturing sulfuric acid) famously uses $V_2O_5$. Deacon's Process (oxidation of $HCl$ to $Cl_2$), however, fundamentally relies on Copper(II) Chloride ($CuCl_2$) as its catalyst, not Iron Oxide.
