Solution

The correct option is B

The oxidation number of oxygen is -2 and nitrogen is +1. The sum of oxidation of atoms in a compound must be equal to zero. In $N_{2} O$ , oxidation is (-2)(+1). We should take an a + 2 charge to cancel out -2 charge of one oxygen ion. Thus, the correct formula is $N_{2} O$ .
