Bonds strength

Postby Norman Dis4C » Sun Nov 17, 2019 11:03 am

Can someone explain to me why double bond is just slightly stronger than single bond? Why does not the strength between the two atoms double?

A double bond isn't twice as strong as a single bond because there are electron electron repulsions in the double bond that slightly reduce the strength.

Since there is still repulsion present between the bonds, the double bond isn't double.

A double bond is stronger than a single bond due to its stability and distance between the bonding atoms. Shorter bond lengths allow attractive forces between atoms to be stronger.

The double bond is stronger than a single bond since it is shorter, therefore having a lesser distance between each of the atoms. The shorter distance makes the bonds less likely to break than a short, single bond.
