Question

Which one is represented correctly in terms of Stock notation?

• A. $FeC{l}_3$ : Iron (II) chloride
• B. $N{O}_2$: Nitrogen peroxide
• C. $N{O}_2$: Nitrogen (IV) oxide
• D. $N{O}_2$: Nitrogen dioxide

Answer 1

Answer: (C)

$N{O}_2$: Nitrogen (IV) oxide

Stock notation is the representation of oxidation number by putting a Roman numeral in parenthesis after the symbol of the metal in molecular formula.
So, correct notation is $N{O}_2$: Nitrogen (IV) oxide.
$FeC{l}_3$ is wrong because it should have been Iron (III) chloride and not Iron (II) chloride.
