Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Recall the catalyst used for polyethylene manufacture.
Polyethylene is commonly manufactured using the Ziegler–Natta catalyst.
This catalyst is used for polymerization of ethene to produce polyethylene.
Step 2: Identify the components of Ziegler–Natta catalyst.
The catalyst consists of a transition metal halide and an organoaluminium compound.
A common combination is:
\[ \mathrm{TiCl_4} \] and
\[ \mathrm{Al(CH_3)_3} \]
Step 3: Explain the role of the catalyst.
\(\mathrm{TiCl_4}\) acts as the transition metal catalyst, while \(\mathrm{Al(CH_3)_3}\) acts as a co-catalyst.
This catalyst system helps in controlled polymerization and formation of linear polyethylene.
Step 4: Eliminate incorrect options.
The other combinations are not standard Ziegler–Natta catalyst systems used in polyethylene manufacture.
Step 5: Final conclusion.
Hence, the catalyst mixture used in the manufacture of polyethylene is
\[ \boxed{\mathrm{TiCl_4,\ Al(CH_3)_3}} \]
