Answer

Explanation:

Step1: Calculate valence - electrons for $[\text{N}-\text{N}=\text{N}]^{-}$

N has 5 valence electrons. There are 3 N atoms and a negative charge. So the total number of valence electrons should be $3\times5 + 1=16$. In the given structure, the number of valence electrons is $2\times2 + 4\times2+2 = 14$. So it has the wrong number of valence electrons.

Step2: Calculate valence - electrons for $\text{N}\equiv\text{N}$

N has 5 valence electrons. For $\text{N}_2$, the total number of valence electrons is $2\times5 = 10$. In the given structure, there are $3\times2 + 2\times2=10$ valence electrons. And each N atom has an octet (triple - bond and a lone - pair), so it is reasonable.

Step3: Calculate valence - electrons for $[\text{Cl}=\text{O}]^{-}$

Cl has 7 valence electrons and O has 6 valence electrons, plus a negative charge. So the total number of valence electrons should be $7 + 6+1 = 14$. In the given structure, there are $4\times2+2\times2 = 12$ valence electrons. So it has the wrong number of valence electrons.

Answer:

  1. No, it has the wrong number of valence electrons. The correct number is: 16
  2. Yes.
  3. No, it has the wrong number of valence electrons. The correct number is: 14
