What are the formal charges of the atoms...

What are the formal charges of the atoms in the nitrite ion in the order of nitrogen, oxygen 1 and oxygen 2?
`overset(1)O=N-overset(2)O` : 0, 0, -1 ; 0, +1, -1 ; -1, 0, -1 ; -1, 0, 0

A

0, 0,-1

B

0,-1,-1

C

-1,0,-1

D

-1,0,0

Text Solution

Verified by Experts

The correct Answer is:
A
The nitrite ion can be represented as
Formal charge on any atom=Number of valence electrons-Number of non-bonding electrons - 1/2 (number of bonding electrons)
Formal charge on nitrogen = `5-2 - 1/2 (6) = 0` Formal charge on oxygen atom 1= 6-4 `-1/2 (4) = 0`
Formal charge on oxygen atom `2 = 6-6 - 1/2 (2) = -1`
