ENLACE COVALENTE COORDINADO O DATIVO | Enlaces Químicos

Learn to identify a coordinate or dative covalent bond. In this video, I explain how a dative or coordinate covalent bond is formed through several examples. This bond occurs between different atoms and is characterized by the fact that the shared electrons are contributed by only one of the bonded atoms. The atom that contributes the pair of electrons is called the donor, and the one that receives it is called the acceptor. A coordinate covalent bond is represented by an arrow that starts from the atom that contributes the two electrons and points toward the atom that does not contribute any. An example of a coordinate bond is when the ammonium cation, NH4+, is formed from ammonia, NH3, and the hydrogen ion, H+. This bond is formed because nitrogen has a free pair of electrons, which it can share with the hydrogen ion (H+). The hydrogen ion results from extracting the single electron possessed by the hydrogen atom; That is, the ion (H+) is able to accept a pair of electrons, which in this case come from the nitrogen atom, and as a result, a new bond is formed in which the electrons come only from the nitrogen. A similar case occurs when a water molecule reacts with an H+ to form the hydronium ion (H3O+).
