When you make sp3 hybrid orbitals all 4 atomic orbitals
become hybridized to yield 4 identical hybrid orbitals.

Formation of a single bond (sigma bond)
Each C in ethylene is sp2 hybridized
The first bond forms from the head on
overlap of the sp2 hybrid orbitals

Each C in ethylene is sp2 hybridized
The first bond forms from the head on
overlap of the sp2 hybrid orbitals
Formation of a single bond (sigma bond)
Hybrid orbitals that come together in a head
on collision will always form a sigma bond
