According to the Lewis acid-base concept

(d) all positively charged ions are acids.

  • Lewis' theory used electrons instead of proton transfer and specifically stated that an acid is a species that accepts an electron pair while a base donates an electron pair.
  • The reaction of a Lewis acid and a Lewis base will produce a coordinate covalent bond, as shown in Figure above. A coordinate covalent bond is just a type of covalent bond in which one reactant gives it electron pair to another reactant. In this case the lewis base donates its electrons to the lewis acid. When they do react this way the resulting product is called an addition compound, or more commonly an adduct.
  • Lewis Acid: a species that accepts an electron pair and will have vacant orbitals
  • Lewis Base: a species that donates an electron pair and will have lone-pair electrons
Answer: molecule in which a central atom has vacant d-orbitals available act as an acid
