In organic chemistry, hyperconjugation is the interaction of the electrons in a sigma bond (usually C–H or C–C) with an adjacent empty (or partially filled) non-bonding p-orbital, antibonding s or p orbital, or filled p orbital, to give an extended molecular orbital that increases the stability of the system. Only electrons in bonds that are ß to the positively charged carbon can stabilize a carbocation by hyperconjugation.
