O having higher FC than N

Postby Isa AbdulCader 3K » Tue Oct 20, 2015 10:07 pm

Why is it that in [NO]+, there is a triple bond where N has an FC of 0 and O has an FC of +1 when O is more electronegative? Why doesn't it form a double bond so that N has the higher FC and O is at 0? For reference, this is 3.48.a, thanks.

Hey Isa,

If you draw both Lewis structures out, you will see that having a double bond between each atom results in a full octet for O, but not N. With a triple bond, they both have full octets.
