I don't really understand the concept behind a coordinate covalent bond. Professor Lavelle skimmed through it during my lecture. Could someone explain this concept to a greater extent and apply it through an example? Thank you!
A coordinate covalent bond is a bond in which both electrons come from one of the atoms. For example, when boron trifluoride reacts with ammonia, the lone pair on ammonia completes boron's octet. Both electrons needed to complete boron's octet come from ammonia, rather than some coming from boron and some from ammonia, therefore making it a coordinate covalent bond.
Coordinate covalent bonds are bonds in which the electrons being shared come from the same atom. In a typical covalent bond, such as the bond between two H atoms, each atom provides one electron that both of the atoms can share to fill their 1s shells. In a coordinate covalent bond, such as the bond between ammonia and H+, the nitrogen in ammonia has two lone pair electrons that are shared with the electron-less H+. In this bond, H+ provides none of the electrons while N provides two for the bond.
A coordinate covalent bond is a type of covalent bond where the two bonding electrons come from the same atom. In a regular covalent bond, each of the atoms that are forming the bond donate an electron to form the bond.
A coordinate bond is formed when one atom donates a lone pair of electrons to an empty orbital of another atom. For example, an ammonia molecule has a lone pair of electron on the N atom, and a hydrogen ion has an empty orbital. As a result, the N atom donates the lone pair of electron to the hydrogen ion so that a covalent bond is formed, the final product is then ammonium ion--NH4+.
A coordinate bond (also called a dative covalent bond) is a covalent bond (a shared pair of electrons) in which both electrons come from the same atom. A covalent bond is formed by two atoms sharing a pair of electrons. The atoms are held together because the electron pair is attracted by both of the nuclei. In the formation of a simple covalent bond, each atom supplies one electron to the bond, but that does not have to be the case.
Coordinate covalent bond is the bond that forms between a lewis acid and a lewis base. This bond is unique as the lewis base donates TWO its electrons to from the bond. This is why a coordinate covalent bond is noted specially rather than just as a normal bond.
