Correct answer: (d) Mg3N2 → –3
Explanation:
(a) \([\overset{+}{Co}(\overset{0}{NH_3})_5\overset{-1}{Cl}]^{+2}\overset{-1 \times 2}{Cl_2}\)
+3 + 5x + 15 - 1 = +2
5x + 17 = +2
5x = -15
x = –3;
Oxidation State of N = -3
(b) NH2OH : x + 3 - 2 = 0
x = -1 Oxidation state of N = -1
(c) (N2H5)+1SO42+
N2H5+: 2x + 5 = +1
x = -2
Oxidation number of N = -2
(d) Mg3N2: 2 × 3 + 2x = 0
2x = –6
x = –3
Oxidation state of N = –3
