Bonds in VSEPR

Postby ShravanPatel2B » Sun Nov 17, 2019 11:35 pm

How exactly do we account for double and triple bonds in when getting the molecular shape?

Double and Triple bonds are accounted for as single bonds. So regardless of the number of bonds, it only counts as one region of electron density.

We don't care about whether it is a single or double or triple bond. We consider them all a single region of electron density.

When determining molecular shape with the VSEPR model, single, double, and triple bonds are all considered to be one area of electron density. This means that regardless of the type of bond, the shape would still be determined as if there was a single bond there.

We consider unbonded electron pairs as well as single, double, and triple bonds to just be individual "regions of electron density" for the sake of VSEPR models

Double, single, and triple bonds are considered one unit, which means that it accounts for one area of electron density even though there might be more bonds being used.

We're only looking for regions of electron density, so all bonds, lone pairs, or single electrons just count as a singular region.

In VSEPR, double and triple bonds would still be represented as “single” bonds demonstrably. Lavelle even said that we should think of these spaces as possible spots of electron density where said density of electrons is highest. This is for VSPER models specifically.

Double and Triple bonds are accounted for in the same way that single bonds are: as a single bonding group/domain.

You don't need to take it into account when determining its shape, they are counted for as one.

Think of the bonding regions as regions of electron density (triple/double bonds are each considered one region, same for single bonds).

thank you, this was very helpful
