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 \[\underset{2\text{ }shared\text{ }electrons}{\mathop{H-N}}\,\,\,\equiv \,\,\underset{6\text{ }unshared\text{ }electrons}{\mathop{C:\,\leftarrow 2}}\,\] unshared electronsH | N | C | |
v | 1 | 5 | 4 |
s | 2 | 8 | 6 |
u | 0 | 0 | 2 |
F | 0 | 1 | -1 |
