The Correct Option is A
Solution and Explanation
A Lewis acid is a species that can accept an electron pair. Among the given options: - AlCl₃ is a Lewis acid because aluminum in AlCl₃ has an incomplete octet and can accept an electron pair. - NH₃ is a Lewis base because it has a lone pair of electrons that can be donated. - OH⻠is also a Lewis base because it has a lone pair of electrons to donate. - H₂O is a Lewis base because it also has lone pairs of electrons on the oxygen atom. Thus, the correct Lewis acid is AlCl₃.
