Calculate the formal charge on each atom...

Calculate the formal charge on each atoms in nitrite ion .

Text Solution

Verified by Experts

(i) Lewis structure of nitrite ion is
`:overset(* *)O=overset(* *)N-overset(* *)underset(* *)O:^(-)`
`"FC on N atoms "=V-L-(1)/(2)S`
`=5-2-(1)/(2)(6)=0`
`"FC on double bonded O atom"=6-4-(1)/(2)(4)=0`
`"FC on single bonded O atom "=6-6-(1)/(2)(2)=-1`
(ii) Lewis structure of carbonate ion is

`"FC on C atom"=4-0-(1)/(2)(8)=0`
`"FC on double bonded O atom"`
`=6-4-(1)/(2)(4)=0`
`"FC on single bonded O atom"`
`=6-6-(1)/(2)(2)=-1`
