Coordinate Covalent Bonds

[205154661_Dis2J]

What is exactly the significance of coordinate covalent bonds and how does it help us understand bond structure in general?

[Chem_Mod]

Coordinate covalent bonds are when a bond is formed from a lone pair from only ONE atom donating BOTH electrons. Remember a bond is two electrons. Take for example NH3 and BF3 bonding to NH3BF3. The bond between the N and B comes from the two electrons from the N, not 1 from N and 1 from B.

[Norman Dis4C]

The ability to form coordinate covalent bonds allows the molecule to form a complex structure, thus the shape of the compound makes it biologically significant.

[BryantChung_4B]

Coordinate covalent bonds allow certain atoms to complete the octet. Boron, a big example, needs to accept a whole lone pair from another atom to complete its octet.

What is the significance of the coordinate covalent bonds? Are these bonds involved in lewis acids and bases?

[Daniel Yu 1E]

Coordinate covalent bonds relates to Lewis acids and bases because they can bond to form a coordinate covalent bond. A Lewis acid is missing a full octet since it has an empty orbital and a Lewis base has a free lone pair to share, thus forming a coordinate covalent bond. A metal ion binding to a chelator is an example.
