Question about bond Length

Postby noelle_lipschutz_3F » Sun Nov 08, 2020 11:44 am

How can you determine bond lengths given a certain bond?

The length of the bond is determined by the number of bonded electrons (the bond order). The higher the bond order, the stronger the pull between the two atoms and the shorter the bond length. Generally, the length of the bond between two atoms is approximately the sum of the covalent radii of the two atoms. :)

Specific bond lengths are usually determined experimentally. You should just know that the more bonds there are, the shorter the bond length is (i.e. a triple bond is shorter and stronger than a single bond).

Bond length is the distance between two nuclei of atoms that are covalently bonded together and it ranges from 0.1 to 0.2 nm. Bond length depends on the bond order or the number of bonded electrons of two atoms. The higher the bond order, the shorter the bond length will be because of the positively charged nuclei's strong pulling force.

I don't think it's always possible to know the exact bond lengths. It is just important to remember that the order of shortest to longest is triple bonds, double bonds, then single bonds.

As was said earlier, I think it's only necessary to remember that bond length is in the order of triple, double, and single with triple being the shortest and single being the longest.

Hi Noelle! You can't really determine the exact length of a bond given a certain bond unless you memorize it from online, but you can definitely determine its relative size through the bond type/strength. For example, if there's a double bond, the bond length will be shorter than it usually would be for a single bond.
