Lewis concept of Acid and Base Identification – Chemistry

            According to Lewis👀 concept:

What is an acid🔥🔥🔥?

An acid is a substance that can accept a pair of electrons.
Lewis acid is always short of electrons therefore acts as an electrophile (electron loving species).

Examples of Lewis Acids:

All the positively charged species and the molecules with the central atoms which needs one or more lone pair of electrons to complete their valence shell are called Lewis acids.
👉Fe+3 etc.

What is a base?
A base is a substance that can donate a pair of electrons.
A lewis base is always an electron rich species that contain one or more lone pairs of electrons therefore it acts as a nucleophile (nucleus loving).

Examples of Lewis Bases:

All the negatively charged species and neutral species bearing one or more lone pairs of electrons are called lewis bases.
👉F- etc.

                Difference between Lewis Acid & Lewis Base:

                    Explanation of Lewis acid & base:

A lewis acid base reaction is the donation of electron pair/s by the base to acid,resulting in the formation of a co-ordinate covalent bond b/w acid and the base.

  1. Spot on with this write-up, I absolutely think this site needs a lot more attention. I’ll probably be returning to read through more, thanks for the information!

  2. Hmm it appears like your site ate my first comment (it
    was extremely long) so I guess I’ll just sum it up what I wrote and
    say, I’m thoroughly enjoying your blog. I as well am an aspiring blog writer but I’m still new to everything.
    Do you have any tips and hints for rookie blog writers?
    I’d definitely appreciate it.
