In the following electron dot structure, calculate the formal charge from left to right nitrogen atom respectively:

Options

A. `-1, -1 and +1`
B. `-1, +1 and -1`
C. `+1, -1 and -1`
D. `+1, -1 and +1`

Explanation

(b) `underset(..)overset(1)overset(..)N=overset(2)N=underset(..)overset(3)overset(..)N`ltbr For `N_((1))` and `N_((3))`, Formal charge `=5-[(4)/(2)+4]=5-6=-1`
For `N_((2))`, Formal charge `=5-(1)/(2)xx8-0=+1`
