Question
Which of the following is a Lewis acid?
Options
AlCl3
MgCl2
CaCl2
BaCl2
Solution
AlCl3
Explanation:
Lewis acids are the species in which the state is not complete and ready to accept electrons. Because Al is surrounded by 6 electrons in AlCl3 and all three Cl atoms are surrounded by 8 electrons, AlCl3 is an electron acceptor. It is a covalent compound.
