MCQ
Oxidation state of nitrogen in NH2​OH is:
  • A
    −3
  • B
    −1
  • C
    +2
  • D
    3
✓

Answer

  1. −1

Explanation:

Let x be the oxidation state of N in NH2​OH.

Since the overall charge on the complex is 0, the sum of oxidation states of all elements in it should be equal to 0.

Therefore, x + 2 − 1 = 0 or, x = −1.
