3-4-ALD. Multiple bonds appear in Lewis structures as a result of which of the following phenomena:

A. An excess of electrons available after single bonds have been formed between the central atom and the surrounding atoms and all atoms' (except hydrogen) octets have been completed

B. A deficiency of electrons available after single bonds have been formed between the central atom and the surrounding atoms and all atoms' (except hydrogen) octets have been completed

C. The number of electrons available equals the number of electrons that are used to form single bonds between the central atom and the surrounding atoms and all atoms' (except hydrogen) octets have been completed

D. None of the above
