Bond lengths

Postby Lelija Kazlauskas 3J » Sun Dec 08, 2019 10:20 pm

Why is it that when you have a molecule that exhibits resonance (e.g. has a double bond and a single bond), the actual bond length is one and a half instead of a double or single bond?

It's hard to put down on paper, but the electrons making the bond are being shared with other atoms so the bond is only inbetween those two atoms half the time

The electron is delocalized among the atoms. Not just one atom will have a double bond, but multiple ones will at different times (hybrid). This makes the molecule more stable.
