Coordinate covalent bond?

Postby Gwynneth Orlino 1B » Fri Jul 12, 2019 8:18 pm

We went over this in lecture today, but I'm still confused on what exactly a coordinate covalent bond is. Can someone help explain this?

Imagine I have ammonia, NH3 and Boron trifluoride, BF3. Ammonia has a lone pair of electrons on the nitrogen atom, and boron in the boron trifluoride only has 6 electrons not filling its octet. So in this scenario when the two molecules react, what occurs is the nitrogen is found to donate both of its electrons to the boron and they both have a filled octet. This occurs due to Nitrogen having a partial negative charge ()
and boron having a partial positive charge ().

So a coordinate covalent bond is a bond in which the electrons shared between two atoms come from one element alone.

In that case, NH3 is the base and BF3 is the acid, yes?

it's when an atom gives both electrons to make the bond. The tow electrons in the bond are from the same atom

A coordinate covalent bond is between an acid and a base where one acts and the lone electron donor and the other acts as the lone electron acceptor.

A coordinate covalent bond is a bond in which the 2 shared e- come from one element alone; this is different from a typical covalent bond in that e- often come from multiple elements. In this scenario, there is a donor (a Lewis base) and an accepter (a Lewis acid). Hope this helps!

Usually, a bond is composed of two electrons, and one coming from each of the bonded atom. A coordinate covalent bond refers to a bond in which BOTH electrons come from ONE atom, as in the case of BF4, when both electrons came from the fluoride ion.

I know understand what a coordinate covalent bond is but, how did you know what compound was a base or an acid?

The acid would be the electron acceptor and the base is the electron donor.

A Lewis acid accepts electrons, while the Lewis base donates electrons, usually as lone pairs.
