Single, double, and triple bonds

Postby Kyle Harvey 4F » Sun Nov 03, 2019 11:36 am

When looking at single, double, and triple bonds, would the same number of bonds be the same length between different elements/atoms? For example, would a single bond be the same length between hydrogen and fluorine and hydrogen and chlorine?

No, it does also depend on the size of the elements themselves.

No. It depends on the radii of the elements themselves.

The greater the electronegativity/electron affinity, the greater the pull on the electrons by the positively charged nucleus.
Since fluorine is more electronegative than chlorine, the H-F single bond will be shorter than the H-Cl single bond.
And as you increase the # of bonds (double, triple), you decrease the bond length because even more electrons are being shared/there is more attraction.

It depends on the atom radii. If the atoms are larger, the bond is weaker because the pull of the nucleus weaker due to how far apart they are from the electrons.

Thank you, this was a helpful clarification
