Lewis Acids and Bases
What are the differences between Lewis Acids and Bases and what does this have to do with the bonds they form?

Re: Lewis Acids and Bases
Lewis acids are electron acceptors, they usually have an unfilled valence and will accept electron pairs from Lewis bases, which are electron donors that give away electron pairs.

Re: Lewis Acids and Bases
Lewis acids are the molecule that has the ability to accept an entire electron pair rather than sharing the electrons. The Lewis base is the donor of the electrons.

Re: Lewis Acids and Bases
Lewis acids are electron pair acceptor. Lewis bases are electron pair donor.

Re: Lewis Acids and Bases
Lewis acids accept a pair of electrons and Lewis bases donate a pair of electrons. So an example would be BF3 and NH3. Where NH3 can form a bond with BF3 by donating its electron pair to boron. In this example BF3 is a Lewis acid and NH3 is a Lewis acid.

Re: Lewis Acids and Bases
A Lewis acid is usually a molecule an unfulfilled valence electron configuration, like BH3, where B can accept another atom to fill its shell, another example would be H+, where it can accept electrons to become neutral. A Lewis base donates electrons, like NH3, where the line pairs on N can allow another molecule to attach, also F- can donate its extra electron to become neutral.

Re: Lewis Acids and Bases
Lewis acids accept an electron pair from lewis bases. When there is an empty orbital, most likely a lewis acid, it will accept an electron pair from a lewis base.

Re: Lewis Acids and Bases
Lewis Acid : electron pair acceptor
Lewis : electron pair donor
Say if you draw the lewis structure NH3 + BF3 , you will notice that the lone pair on N from NH3 will be accepted by BF3, making NH3 the base and BF3 the acid
