Bond Length and Bond Strength

Postby Steven Garcia 1H » Wed Nov 07, 2018 11:49 pm

Just to clarify, we can assume the bond length will more than likely always be inversely proportional to the bond strength ? (increased bond length--> reduced bond strength)

Yes, the more electrons two atoms share, the closer they will be drawn to one another, thus decreasing bond length.

Yup!
Also, single bonds are considered the weakest because they are the longest. Following the weakest in strength, would be double bonds, then triple bonds and etc. because each bond has more electrons to pull/ share the electrons between molecules/ atoms.

Bond length and strength can also be tied to different kinds of bonds as well such as ionic bonds compared to covalent bonds, dipole moments, Van der Waals forces, and hydrogen bonds. An increasing bond length yields a weaker bond.

thats correct! and the shorter the bond the stronger it is

Yes! This is because longer bond lengths (single bonds) are only sharing one pair of electrons and therefore the bond is weaker. Double bonds are sharing two pairs of electrons so they are stronger and the distance between them is shorter.
