Chapter 5, Problem 5.57QP

(a)

Interpretation Introduction

Interpretation:

From the ball-and-stick model derive the molecular formula and name it.

Concept introduction:

• Molecular formula is a chemical formula which shows nature and total number of atoms in a molecule.
• Example: ${\text{Benzene -C}}_{\text{6}}{\text{H}}_{\text{6}}$, $\text{thiophene -}{\text{C}}_{\text{4}}{\text{H}}_{\text{4}}\text{S}$
• It has prefix for each number of atom viz. mono-(1), di-(2), tri-(3), etc.
• The structure of name of binary compound is prefix + first element name + prefix + second element root name + ide.
• Examples for root name:

figure 1

• First element name should be given for more electropositive element.
• Second element name should be given for more electronegative element.

To derive: the molecular formula of figure (a)
