NEET 2019 · ChemistryPrevious Year Question
Match the catalyst with the process: Catalyst (i) (ii) (iii) (iv) Nickel complexes Process (a) The oxidation of ethyne to ethanal (b) Polymerisation of alkynes (c) Oxidation of in the manufacture of (d) Polymerisation of ethylene Which of the following is the correct option?
Answer: (A) (a) i-c, ii-d, iii-a, iv-b. \textbf{Answer:} (a) i-c, ii-d, iii-a, iv-b \textbf{Solution:} catalyses the oxidation of in the Contact process for , so i-c.
- A.(a) i-c, ii-d, iii-a, iv-b✓
- B.(b) i-a, ii-b, iii-c, iv-d
- C.(c) i-a, ii-c, iii-b, iv-d
- D.(d) i-c, ii-a, iii-d, iv-b
Correct Answer
(A) (a) i-c, ii-d, iii-a, iv-b
Solution & Explanation
\textbf{Answer:} (a) i-c, ii-d, iii-a, iv-b \textbf{Solution:} catalyses the oxidation of in the Contact process for , so i-c. is the Ziegler-Natta catalyst used for the polymerisation of ethylene, so ii-d. catalyses the Wacker oxidation of ethyne to ethanal, so iii-a. Nickel complexes catalyse the polymerisation of alkynes, so iv-b. The correct match is i-c, ii-d, iii-a, iv-b.
