The Lewis base list is commonly referred to in the study of chemistry and contains substances which donate an electron pair which is then shared by the base and the covalent bond. To learn more about some of the bases, which are contained in the Lewis base list, simply continue reading to discover everything you need to know about the Lewis base list.
Everything you need to know about the Lewis bases:
1. Most types of oxygen and nitrogen can act as Lewis bases
If a type of oxygen or nitrogen feature organic compounds, the oxygen or nitrogen type in question can be used as a Lewis base as it will feature a pair of electrons.
2. Atoms, ions and molecules can all act as Lewis bases
You may be surprised to read that atoms, ions and molecules can all be used as Lewis bases.
3. For an atom, ion or molecule to be used as a Lewis base, there also needs to be an atom which will accept a Lewis bases’ pair of electrons
If an atom, ion or molecule isn’t able to donate its pair of electrons to another atom, which will accept them, the atom, ion or molecule in question won’t become a Lewis base.
4. You can find out whether or not an atom, ion or molecule is by drawing the Lewis structure
If you’re curious about how you can accurately discover whether a particular atom, ion or molecule is a Lewis base, you can draw the Lewis structure in order to see whether you can find a pair of electrons which can be used to form a bond to another atom. If you can identify a pair of electrons which can be donated to another atom, the atom, ion or molecule which you’re researching can in fact act as a Lewis bond.
As an example, ammonia may be able to be used in a Lewis base if it’s able to donate a pair of electrons to the element H+, in order to form a bond with the element H+.
5. In organic chemistry compounds with pi electrons are usually Lewis bases
If you study organic chemistry, you’ll discover that the vast majority of compounds which boast pi electrons can be classified as Lewis bases.
6. Some compounds can be used either as a Lewis base or a Lewis acid
To further complicate things, some compounds, including atoms, ions and molecules actually have the potential to turn into either a Lewis base or a Lewis acid. As an example, most forms of alcohol act as acids when they donate H+ but can also act as a Lewis base when their oxygen atom decides to accept H+.
So if you’re interested in learning further information about Lewis bases, it’s well worth researching further types of compounds which can be turned into Lewis bases and Lewis acids.
So if you were confused about how compounds such as ions, molecules and atoms can be used as Lewis bases, hopefully you now have a clear understanding of Lewis bases.
