Bases and Acids

Postby JasonNovik3A » Fri Nov 03, 2017 11:48 pm

What's the difference between Lewis Acids and Bases and how do we identify them?

A Lewis Acid is a molecule that accepts an electron pair.
A Lewis Base is a molecule that donates an electron pair.

Acids and bases can be considered in certain reactions to see how they form coordinate covalent bonds.

I hope these examples of Lewis Acids and Bases also help!
Examples of Lewis Bases: NH3, F-, and OH-
Examples of Lewis Acids: BF3 and H+.

In general, Lewis acid is the "electron accepter" and Lewis base is the "electron donor".

Commonly, most of cations and metal ions are Lewis acids (accepting electrons)
most of nonmetal ions, neutral molecule with unpaired electrons (e.g. NH3), and some molecules with C=C bonds are Lewis bases(donating electrons)
