The correct answer is acid.
The correct answer is acid.
A substance that accepts an electron pair is called a Lewis acid. Lewis acids are typically electron-deficient species, such as metal cations or molecules with incomplete octets, that can form coordinate covalent bonds by accepting electron pairs from Lewis bases, which donate the pairs. This interaction is fundamental in many chemical reactions, including catalysis and complex formation.

The correct answer is acid.
A substance that accepts an electron pair is known as a Lewis acid. Lewis acids are typically electron-deficient species that can form coordinate covalent bonds with electron-rich species, or Lewis bases, which donate an electron pair. Examples of Lewis acids include metal cations, certain nonmetals like boron trifluoride (BF3), and transition metal complexes. This interaction is fundamental in many chemical reactions, including catalysis and coordination chemistry.
As the definition of a Lewis acid says:"Capable of accepting electron pair (from a (Lewis) base".So H+ and Ag+ are both Lewis acids compared in the following reaction with ammonia:(in which the N-atom is donating the unbound electron pair as being a 'Lewis' base)H+ + NH3 --> HNH3+Ag+ + 2NH3 --> Ag(NH3)2+[As you can see the 'Lewis' definition is much wider than the 'Bronsted/Lowry': it needs free places for an electron pair, not H+]
