Respuesta :
The definition of a Lewis acid is a substance that accepts an electron to form a covalent bond. So, this definition directly permits you to answer the question. The term that best describes a compound that accepts electrons from another substance to form a covalent bond is Lewis acid.
Answer:
Lewis acids describe this compound’s behavior
Explanation:
According to Lewis's theory, a base is a substance that has an unshared pair of electrons, with which it can form a covalent bond with an atom, a molecule or an ion. An acid is a substance that can form a covalent bond by accepting a pair of electrons from the base. So, a Lewis acid-base reaction is represented by the transfer of a pair of electrons from a base to an acid, forming a covalent bond.
The reaction is:
A + :B ↔ A-B
Chemical species that function as Lewis acids include:
Molecules or atoms that have incomplete octets, several simple cations, some metal atoms and compounds that have central atoms capable of extending their valence levels.
