A) H
B) N
C) C
D) All have same value
Correct Answer: C
Solution :
Formal charge, \[F=V-\frac{s}{2}-U\] Where, v = valency electrons s = shared electrons u = unshared electrons \[\underset{\text{2}\,\text{shared}\,\text{electrone}}{\mathop{H-N}}\,\equiv \underset{\text{6}\,\text{unshared}\,\text{electrons}}{\mathop{C:\leftarrow 2}}\,\]H | N | C | |
v | 1 | 5 | 4 |
s | 2 | 8 | 6 |
u | 0 | 0 | 2 |
F | 0 | 1 | \[-1\] |
