Observe the following structure The formal charges on the atoms 1,2,3 respectively are

Options

  1. A+1,0,-1
  2. B0,0,-1
  3. C-1,0,+1
  4. D0,0,0

Correct answer

B. 0,0,-1

Step-by-step solution

The Formal charge can be calculated by this Formula aligned Formal charge = & [ array l Total number of Valence electron in the free state array ]- [ array l Total number of non - Bonding (lone pair) electron array ] & - 1 2 [ array c Total number of Bonding ( shared) electrons array ] aligned For atom 1 6-41 / 2[4]=0 Atom 2 5-2-1 / 2[6]=0 Atom 3 6-6=1 / 2[2]=-1
