Answer 1

Vanadium pentoxide with chemical formula ${{V}_{2}}{{O}_{5}}$ is usually used in the contact process. $TiC{{l}_{4}}/Al{{(Me)}_{3}}$ is the chemical formula for the Ziegler-Natta catalyst and is used in Ziegler-Natta polymerization. Palladium chloride with the chemical formula $PdC{{l}_{2}}$ is a catalyst used in the Wacker process. Iron oxide is usually used in Haber’s process.

Complete step by step answer:
So, having seen the hint let us consider each of the catalysts used in the process and see for what purpose the process they are used.

- Contact process is the method used for the commercial production of sulphuric acid having chemical formula ${{H}_{2}}S{{O}_{4}}$, In large quantities and in high concentrations. And the main and common catalyst used in the contact process is vanadium pentoxide (${{V}_{2}}{{O}_{5}}$).

- Ziegler-Natta polymerization is a polymerization which involves Ziegler-Natta catalyst and the process involves the synthesis of polymers of alpha-olefins or alkenes. For example, the catalyst can be used for the polymerization of ethane to produce polyethylene.

- Wacker process or Wacker oxidation is an industrial process for the synthesis of ethanal from ethene. And the catalyst used in this process is palladium as $PdC{{l}_{2}}$ in the presence of oxygen.

- Haber’s process or Haber-Bosch process is one of the efficient industrial processes for the production of ammonia ($N{{H}_{3}}$). And the catalyst used is magnetite i.e. iron oxide.
Thus, ${{V}_{2}}{{O}_{5}}$- ${{H}_{2}}S{{O}_{4}}$, $TiC{{l}_{4}}/Al{{(Me)}_{3}}$- Polyethylene, $PdC{{l}_{2}}$-Ethanal and iron oxide- $N{{H}_{3}}$.
So, the correct answer is “Option B”.

Note: It should be noted that the Ziegler-Natta catalyst consists of two parts, where one is a transition metal compound having titanium chloride and the other part is an organo-aluminium compound (that act as the co-catalyst). Palladium chloride reduces the activation energy of the intermediate formed during the Wacker process.
