Question

Identify from the following list of molecules and ions which behave as Lewis acids: CO₂, NH₃, BCl₃, Fe ₃⁺

Answer 1

BCl₃ and Fe³⁺ behave as Lewis acids.

Step-by-step explanation:

In the Lewis acid-base theory, a Lewis acid is a molecule or ion that accepts an electron pair, while a Lewis base is a molecule or ion that donates an electron pair. From the given list of molecules and ions, BCl₃ and Fe³⁺ behave as Lewis acids.
