Question

explain Lewis acid Base theory with examples​

Answer 1

Answer:

A Lewis acid is a chemical species that contains an empty orbital which is capable of accepting an electron pair from a Lewis base to form a Lewis adduct.

Examples include copper (Cu2), iron (Fe2+ and Fe3+), and hydrogen ion (H+). An atom, ion, or molecule with an incomplete octet of electrons can accept electrons. Examples include boron trifluoride (BF3) and aluminum fluoride (AlF3).

Answer 2

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.
