Lewis acids and bases

Postby Ashley McClearnen 1B » Sun Nov 04, 2018 3:32 pm

What are some other examples of Lewis acids and bases other than the examples from lecture?

A lewis base is a molecule that will donate a pair of electrons to another atom. Some examples are NH3 and F-.
A lewis acid is a molecule that will accept a pair of electrons. Some examples are AlCl3 and BH3.

How to easily identify Lewis acids and bases? How do they affect Lewis structures?

Lewis acids are electron acceptors, so they will not have a complete octet/ be in need of electrons to be more stable
Lewis bases are electron donors, and will have a pair of electrons to share with a lewis acid.

They will affect lewis structures because they will be in a complex together, and the combination of the acid and base should result in octet formation for both the acid and the base.
