Conjugation occurs when p orbital on three or more adjacent atoms can overlap Conjugation tends to stabilize molecules
Allylic carbocations are a common conjugated system.
The positive charge of a carbocation is contained in a P orbital of a sp2 hybrizied carbon. This allows for overlap with double bonds. The positive charge is more stable because it is spread over 2 carbons.
