Pi and Sigma Bonds and their affect on energy

Postby 605208780 » Tue Dec 03, 2019 12:33 pm

Will someone please explain how pi bonds and their p orbitals cause a lower energy state

In a pi bond the p orbitals overlap above and below the atom, localizing the electrons above and below the plane of the bond—a higher energy state compared to the overlap of a sigma bond. You can also conceptualize that pi bonds are weaker because their electrons are in a higher energy state.

Pi bonds cause the delocalization of electrons, which makes the overall molecule more stable and exist at a lower energy level.

Thanks- I was also confused on this topic.
