The Lewis structure for O ₃ molecule is given below. The correct formal charges on oxygen atoms labelled 1, 2, 3 are respectively.

Options

  1. A–1, 0, + 1
  2. B+1, 0, – 1
  3. C+1, – 1, 0
  4. D0, + 1, – 1

Correct answer

A. –1, 0, + 1

Step-by-step solution

Formal charge = No. of valency electron in central atom - [ . No. of lone pair + 1 2 No. of bond pair of electron] F.C for O labelled as 1=6-[6+1]=-1 F.C for O labelled as 2=6-[4+2]=0 F.C for O labelled as 3=6-[2+3]=+1
