InterviewSolution

1.	In which substance does nitrogen exhibit the lowest oxidation state ?A. Nitrogen gasB. AmmoniaC. Nitrous oxideD. Nitric oxide
Answer» Correct Answer - B Oxidation state of nitrogen gas `(N_(2))` is zero, as both the nitrogen atom possess same electronegativity as well as same number of electrons. The oxidation states of ammonia. Nitrous oxide and nitric oxide are given below Ammonia `(NH_(3))` `x=3(1)=0` `x=-3` Nitrous oxide `(N_(2)O)` `2(x)+1(-2)=0` `2x=2` `x=+1` Nitric oxide (NO) `x+(-2)=0` `x=+2` Thus, nitrogen exhibits lowest oxidation state in case of ammonia
