Question

what is lewis concept of acid and base

Answer 1

In the Lewis theory of acid-base reactions, bases donate pairs of electrons and acids accept pairs of electrons. A Lewis acid is therefore any substance, such as the H+ ion, that can accept a pair of nonbonding electrons. In other words, a Lewis acid is an electron-pair acceptor.

Answer 2

here is the ans

According to Lewis theory of acids and bases, acid is a species which accepts electron pair and base which donates an electron pair. 

For example, consider the following reaction

 BF3 + :NH3 → BF3:NH3

In the above reaction, NH3 is donating a pair of electrons to BF3, hence NH3 is a lewis base and BF3 is a lewis acid. ..
