Answer

Explanation:

Step1: Recall resonance structure rules

Resonance structures have the same connectivity of atoms but different arrangements of electrons. The total number of valence - electrons must be conserved. Nitrogen has 5 valence electrons and sulfur has 6 valence electrons. For (N_2S), the total number of valence electrons is (2\times5 + 6=16) valence electrons.

Step2: Analyze each structure

  • For (:N\equiv S - \ddot{N}:): The number of valence electrons is (2\times5 + 6 = 16).
  • For (:\ddot{N}-N\equiv S:): The number of valence electrons is (2\times5+6 = 16).
  • For (:\ddot{N}-N-\ddot{S}:): This structure has only 14 valence electrons ((2\times5 + 4)), so it is not a valid resonance structure for (N_2S).
  • For (:\ddot{N}-S-\ddot{N}:): This structure has 14 valence electrons ((2\times5+4)), so it is not a valid resonance structure for (N_2S).
  • For (:\ddot{N}-S\equiv N:): The number of valence electrons is (2\times5 + 6=16).
  • For (:N\equiv N-\ddot{S}:): The number of valence electrons is (2\times5 + 6 = 16).
  • For (\dot{N}=N=\dot{S}): This structure has 14 valence electrons ((2\times5 + 4)), so it is not a valid resonance structure for (N_2S).
  • For (\dot{N}=S=\dot{N}): This structure has 14 valence electrons ((2\times5 + 4)), so it is not a valid resonance structure for (N_2S).

Answer:

(:N\equiv S - \ddot{N}:), (:\ddot{N}-N\equiv S:), (:\ddot{N}-S\equiv N:), (:N\equiv N-\ddot{S}:)
