What happens in a Lewis acid-base reaction?A. An acid accepts an electron pair from a base.B. An acid donates an H+, and a base donates electrons.C. An acid donates an H*, and a base donates an OH".D. An acid donates an H*, and a base accepts an H*.



Answer :

Answer

A. An acid accepts an electron pair from a base.

Explanation

In Lewis's acid-base reaction theory, 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. -This means, a Lewis acid is an electron-pair acceptor.

Therefore, the correct answer is:

A. An acid accepts an electron pair from a base.
