The formal charges of N _ (1) , N _ (2) and O atoms in are respectively

Options

  1. A+1,-1,0
  2. B-1,+1,0
  3. C+1,+1,0
  4. D-1,-1,0

Correct answer

B. -1,+1,0

Step-by-step solution

aligned & Formal charge = [ array l Total number of valence electrons in the free atom array ] & - [ array l Total number of non-bonding (lone pair)electrons array ]- 1 2 [ array l Total number of bonding (shared) electrons array ] aligned In structure the formal charge on.... the end N atom marked 1 , aligned & =5-4- 1 2 (4) & =5-4-2=-1 aligned the central N atom marked 2 , aligned & =5-0- 1 2 (8) & =5-4=+1 aligned the end O atom, aligned & =6-4- 1 2 (4) & =6-6=0 aligned
