VSEPR RULE 3

[yast_27]

Hi,
I don't understand why single and multiple bond are considered the same as they have different electon "concentration", why aren't double bond more repulsive than single bond?

Thank you very much

I'm not 100% sure but I think the reason that single and double bonds are both considered 1 area of e- density is because for double bonds as well as single bonds, the e- are still in the one same area. VSEPR counts areas of e- density, and a double bond is 1 area of e- density just as single bonds are.

A double bond will count as one electron density so it doesn't affect the shape of the molecule.

If would make sense if single, double, triple bonds are considered the same as each of these bond still has the same purpose of linking atoms to the other atoms. Each atom holds electrons and therefore each bond is linked to one region of electron density.

Single, double, and triple bonds are one area of bonding, so they all count as one region of electron density.
