In the following electron dot structure, calculate the formal charge from left ot righ nitrogen atom.
`underset(..)overset(..)(N)=N=underset(..)overset(..)(N)`

A

`-1,-1,+1`

B

`-1,+1,-1`

C

`+1,-1,-1`

D

`+1,-1,+1`

Text Solution

Verified by Experts

The correct Answer is:
B
Formal charge on an atom- total no. of valence electron in free atom- total no. of non bonding electrons `-1/2` total no. of bonding electrons
`underset(1)underset(..)overset(..)(N)=underset(2)(N)=underset(3)underset(..)overset(..)(N)`
`N_(1)=5-4-1/2xx4=5-6=-1`
`N_(2)=5-0-1/xx8=5-4=+1`
`N_(3)=5-4-1/2xx4=-1`
