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.

A Lewis acid accepts an electron pair.
Which substance accepts an electron pair?
A Lewis acid.
What kind of substance accepts an electtom pair?
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.
What would be considered a base and an acid?
There are three definitions for acids and bases. Arrhenius definition: An acid is a substance that produces hydrogen (H+) ions in water while a base produces hydroxide (OH-) ions. Bronsted-Lowry definition: An acid gives up or donates a proton (H+) to another molecule while a base accepts a proton. Lewis definition: An acid accepts an electron pair in bonding to another molecule/ion while a base donates and electron pair. Note that if a substance meets one of the first two definitions it probably meets the others as well.
What are the characteristics of Bronsted-Lowry base?
A Bronsted-Lowry base is a substance that accepts a proton in a chemical reaction. It can donate a pair of electrons to form a new bond with a proton. In water, Bronsted-Lowry bases can form hydroxide ions (OH-) when they accept a proton.

Which substance accepts an electron pair?
A Lewis acid.
What substance accepts an electron pair?
The correct answer is acid.
What kind of substance accepts an electron-pair?
The correct answer is acid.
What kind of substance accepts an electtom pair?

How can one identify whether a substance is a Lewis acid or base?
A substance can be identified as a Lewis acid if it accepts an electron pair, and as a Lewis base if it donates an electron pair. Lewis acids are electron pair acceptors, while Lewis bases are electron pair donors.
What is basic substances?
There are three definitions. A substance that produces hydroxide (OH-) ions in water. A substance that accepts a proton (H+ ion). An electron pair donor.
What is a basic substance?
There are three definitions. A substance that produces hydroxide (OH-) ions in water. A substance that accepts a proton (H+ ion). An electron pair donor.
What definition best describe an acid?
An acid is a substance that donates a proton or accepts an electron pair in a chemical reaction. Acids typically have a sour taste and can turn blue litmus paper red.
What kind of substance accepts electron pair?
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+]

What happens in a Lewis acid-base reaction?
