finding bond length

[805098281]

How do you calculate the different bond lengths of a molecule?

[Andrea Zheng 1H]

Normally bond lengths are given based on experimental data.

In addition, you can find the bond length of a molecule using its other properties such as ionization energy difference. So, if the ionization energy is greater, then the bond length will be shorter.

I remember in lecture Dr. Lavelle said something about looking the bond length up which I'm guessing means we need to be given enough information to solve for it if not I think it might be given to us.

[Esther Lee 4H]

From what I remember about high school chemistry though, bond length is determined by the bond order. So if there's more bonds between electrons, the stronger the pull, and therefore a shorter bond length. triple bond < double bond < single bond. single bond should be the longest because there are only 2 electrons pulling it together.

[Riley Dean 2D]

also if the structure has some single bonds and some double bonds the overall bond length will be somewhere between the given values for two types of bonds

[Christopher Wendland 4F]

For covalent bonds, bond energies and bond lengths depend on many factors: electron afinities, sizes of atoms involved in the bond, differences in their electronegativity, and the overall structure of the molecule. There is a general trend in that the shorter the bond length, the higher the bond energy.

For ionic bonds, bond length is dependent on the bond order. Whether it is a single, double or triple bond. Single bonds are the longest and triple bonds are the shortest.
