CN- Resonance structures

Postby Nandhini_2K » Tue May 15, 2018 3:21 pm

Can C have 1 Lone pair and 1 bond? Does this violate the octet rule?

Yes, that is allowed! Another resonance structure with the same formal charge can be a triple bond with a lone pair for each element.

The octet rule states the each element must have 8 surrounding electrons. One lone pair is 2 electrons and one bond is 2 electrons, so C would only have 4 electrons. So C would need more bonds or lone pairs. C typically prefers to have 4 bonds more than 4 lone pairs so it is more likely that C would form a triple bond with N.
