Q50 / 150 · MHT CET 2026 (13 April Shift 2) · Chemistry
Name the catalyst used in the manufacture of HDPE polymer.
- Correct answerATriethyl aluminum with titanium tetrachloride
- BTriethyl aluminum with zinc chloride
- CTriethyl aluminum with nickel chloride
- DTriethyl aluminum with stannic chloride
Solution
High-density polyethylene (HDPE) is manufactured by the coordination polymerization of ethene using a Ziegler-Natta catalyst.
The Ziegler-Natta catalyst is a mixture of triethyl aluminum, $(C_2H_5)_3Al$, and titanium tetrachloride, $TiCl_4$.
Answer: Triethyl aluminum with titanium tetrachloride
The Ziegler-Natta catalyst is a mixture of triethyl aluminum, $(C_2H_5)_3Al$, and titanium tetrachloride, $TiCl_4$.
Answer: Triethyl aluminum with titanium tetrachloride
Hence, the correct answer is option: 'A'.
