Hybrid Orbitals

Postby Jasmine 2C » Sun Dec 01, 2019 12:31 am

I remember one lecture example had 3 hybrid orbitals and an extra one (I forgot the name of the orbital), but there was an extra orbital with one unpaired electron because the first 3 hybrid orbitals all contained one unpaired electron. What is the reason for this extra orbital and what other times will we need them?

If it had 3 hybrid orbitals it is sp2. The unhybridized orbital is left over because only 2 of the p sub shells were hybridized but one wasn’t

You would place the extra unpaired electron in the unhybridized orbitals in cases where each hybridized orbital subshell has one paired electron or just when it would make the atom of be more stable bc or lower energy.

The electron repulsion that would be caused if u tried putting all the electrons in the hybridized shells would increase the energy of the atom and not work for explaining how the atom can form so many bonds. Or which bonds. By leaving out a p subshell, the atom has the opportunity for forming pi ponds.

The extra orbital is needed for the 4th electron in an sp2 orbital, which can hold 3 electrons. The un-hybridized p electron is unpaired.
