NEET Chemistry Redox Reactions Questions Solved

NEET - 2012

In which of the following compounds, nitrogen exhibits highest oxidation state?

(a) N2H                (b) NH3

(c) N3H                   (d) NH2OH

Let the oxidation state of nitrogen in the given compounds be x.

(a)  x  +1

      N2H4

              2x + (+1)4 = 0

                       2x = -4

                ...     x = -2

(b)  x +1

      NH3              x + (+1)3 =0

                          ... x = -3

(c)  x +1

      N3H               x3 + (+1)0 = 0

                             3x = -1

                        ... x = -1/3

(d)  x+1-2+1

      NH2OH              x + (+1)2+(-2)+(+1) =0

                                 x+2-2+1=0

                         ... x =-1
