The sp2 orbital can contain unpaired electrons in a Lewis Acid, Examples are molecules that have odd electron pairings such as NO.

sp^2 orbitals are always present as a set of three. In ethylene, H2C=CH2, for example, three sp2 orbitals link the C to the 2 H's and the other C. In addition two p-orbitals form a pi-bond between the two C's.
