MCQ
According to Lewis concept, an acid is a substance which
- AAccepts protons
- BDonates protons
- ✓Accepts a lone pair of electrons
- DDonates a lone pair of electrons
✓
Answer
Correct option: C.
Accepts a lone pair of electrons
c
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.
