Hyperconjugation in organic chemistry is the stabilizing interaction that results from 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 or antibonding orbital or filled orbital to give an extended molecular orbital that increases the stability of the system. Only electrons in bonds that are to the positively charged carbon can stabilize a carbocation by hyperconjugation.
