WebOct 23, 2015 · Postby Chem_Mod » Fri Oct 23, 2015 11:12 pm. In sp 2 hybridization, one p-orbital is left unhybridized. Therefore, ethene is left with two adjacent unhybridized p-orbitals. These will overlap to create a pi orbital, and this is where the remaining two electrons lie. This is why we say that in a double bond, one line is sigma and one line is pi. rock city valmeyer
