JEE Main 2015 — D And F Block Elements Question with Solution

To match the catalysts to the correct processes :

1. $TiC{l}_3$ is well-known as a catalyst in Ziegler-Natta polymerization which is used for the production of polymers of olefins. So, $(A)-(ii)$.




2. $PdC{l}_2$ is used in the Wacker process, which is used to convert ethene to acetaldehyde. Hence, $(B)-(i)$.




3. $V_2{O}_5$ is used in the Contact process to manufacture sulfuric acid by catalyzing the oxidation of sulfur dioxide to sulfur trioxide. Therefore, $(D)-(iii)$.




4. $CuC{l}_2$ is used in Deacon's process for the oxidation of hydrochloric acid to chlorine. Hence, $(C)-(iv)$.

Comparing these pairings with the options given, we find that the correct option is :

$$\left(A\right)-\left(ii\right),\left(B\right)-\left(i\right),\left(C\right)-\left(iv\right),\left(D\right)-\left(iii\right)$$
