Answer:
Explanation:
::N=N=O:: (-1, +1, 0)
:::N-N=-O: (-2,+1,+1)
:N=-N-O::: (0,+1,-1)
= represents double bonds
=- represents triple bonds
: represents electrons on the atoms to complete octet
numbers in the parantheses are thhe formal charges
third one is the appropriate because formal charges ae close to zero and oxygen, the most electronegative element in this compound, has largest negative formal charge
bond length: 110
