Unformatted text preview: level of the bonded state with the number in the atomic state. Atomic carbon has 4 electrons in the valence level . Since in the carbocation, only 3 electrons belong to carbon, there is a deficiency of one electron (a formal charge imbalance at carbon). Therefore, there is a formal charge of +1 on carbon. Carbanions C:-a carbanion Three of the bonding electrons and the two nonbonding electrons belong to carbon. Calculation of Formal Charge Carbanions have 6 bonding and two nonbonding electrons in the valence level, and have a formal charge of -1 . Since atomic carbon has 4 electrons in the valence level while 5 of the 8 valence electrons in the carbanion belong to carbon, there is a surplus of one electron in the bonded state. The formal charge is -1 ....
