single bonds and s bonds

Postby Hannah_1G » Fri Dec 06, 2019 12:08 am

How do you total in the strength in a bond when factoring how many bonds and the s- orbital characteristic of it? If I'm not mistaken having a hybridized orbital sp is stronger than sp2 but is a double bond stronger than a single bond of 2p-2p?

In general:
Sigma bonds are usually stronger than pi bonds.
Double bond stronger than single.
Triple bond stronger than double.

I discussed this trend in class using the organic examples:
CH3CH3
CH2CH2
CHCH

There is no trend in hybridization type and bond strength.
For example:
H-F is a stronger bond than H-Br and both halogens would be described as sp3 to get the correct tetrahedral arrangement of electron density around each halogen.
