Chapter 5, Problem 44QAP

(a)

Interpretation Introduction

Interpretation : The formula of dinitrogen oxide needs to be determined.

Concept Introduction : The name of the binary compound is written in such a way that first name of the element which is written first in the formula is written followed by the element whose symbol is written after it. The number of atom of elements are written by adding prefix mono, di, tri, tetra and so on depending on the number of atoms. The second atom of element is written with suffix -ate or -ide depending on the oxidation state and the group to which element belongs in the periodic table.

Thus, formula can be easily written from the name of the binary compounds.
