Which of the following is Lewis acid?
Correct answer: D. All of these
- A. FeCl₃
- B. AlCl₃
- C. BF3
- D. All of these
Explanation
The correct answer is All of these because all the compounds listed (FeCl₃, AlCl₃, and BF3) are Lewis acids. A Lewis acid is defined as a substance that can accept a pair of electrons to form a covalent bond. In FeCl₃, the iron atom is electron-deficient and can accept an electron pair. Similarly, AlCl₃ has an electron-deficient aluminum atom that can accept an electron pair, and BF3 has a boron atom with an incomplete octet, making it capable of accepting an electron pair. Therefore, each of these compounds can act as a Lewis acid.
