Question

In the chemical change NH3 gives 1/3 HN3, Oxidation state of nitrogen changes by a factor,
1) 3
2) 1/3
3) 9
4) 1/9​

Answer 1

Explanation:

3

N is the more electronegative of these two elements, and the common negative oxidation state of N is -3 ( as in NH3). This makes the oxidation state of carbon +2, since +2 + (-3) = -1, the charge on the ion.
