AlBr3 which is used in the alkylation of benzene possesses the properties of:
Correct answer: D. All of the above
- A. A catalyst
- B. A Lewis acid
- C. An electron deficient specie
- D. All of the above
Explanation
AlBr3 is used as a catalyst, it is a lewis acid i.e is an electron-pair acceptor therefore it is also an electron deficient species so option D is correct

About Bronsted-Lowry and Lewis Concepts
The Brønsted-Lowry concept defines acids as proton donors and bases as proton acceptors, producing conjugate acid-base pairs. The Lewis concept extends the idea to electron-pair acceptors and donors, so compounds such as BF3 and NH3 can be treated as acid and base even without proton transfer, unlike the Arrhenius definition.
