The formal charges of N(1) N(2) and O at...

 The formal charges of `N_(1) N_(2)` and O atoms in `: overset(..)(N)_(1) = N_(2) = O overset : :` are respectively

A

`+1,-1,0`

B

`-1,+1,0`

C

`+1,+1,0`

D

`-1,-1,0`

Text Solution

Verified by Experts

The correct Answer is:
(b)
Formal charge (FC) = No of valence electrons - Lone pair `- (1)/(2)` bond pair
`:overset(..)N_(1)=N_(2)=overset(..)O:`
therefore FC of `N_(1)=5-4-(1)/(2)(4)=-1`
FC of `N_(2)=5-0-(1)/(2)(8)=+1`
FC of `O=6-4-(1)/(2)(4)=0`
