TiCl4 is used as catalyst for manufacture of
Correct answer: B. Plastics
- A. Sulphuric acid
- B. Plastics
- C. Ethanol
- D. Tetraethyl lead
Explanation
TiCl4 is a key component in the Ziegler-Natta catalyst system, which is essential for the polymerization of ethylene into polyethylene, a common plastic. This process involves the use of (C2H5)3Al and TiCl4 as catalysts under controlled conditions. The other options are incorrect because TiCl4 is not used in their respective production processes. Sulphuric acid production uses vanadium(V) oxide, ethanol is produced via different methods, and tetraethyl lead is synthesized through other chemical reactions.

About Transition Elements
Transition elements are identified by their partially filled d subshells in atoms or common ions. The topic covers the electronic structure of d-block elements, including the filling order of 4s and 3d orbitals, variable oxidation states and the distinction between transition elements and elements with completely filled d subshells.
