Question
Which ordering of compounds is according to the decreasing order of the oxidation state of nitrogen?
A.
$$HN{O_3},NO,N{H_4}Cl,{N_2}$$
B.
$$\,HN{O_3},NO,{N_2},N{H_4}Cl$$
C.
$$HN{O_3},N{H_4}Cl,NO,{N_2}$$
D.
$$NO,HN{O_3},N{H_4}Cl,{N_2}$$
Answer :
$$\,HN{O_3},NO,{N_2},N{H_4}Cl$$
Solution :
$$HN\mathop {{O_3}}\limits^{ + 5} ,\mathop N\limits^{ + 2} O,\mathop {{N_2}}\limits^0 ,\mathop N\limits^{ - 3} {H_4}Cl$$
