Interpretation Introduction

To determine: The line-angle structure for the given condensed structural formula $\left({\text{CH}}_{\text{3}}{\left({\text{CH}}_{\text{2}}\right)}_{\text{3}}\text{CH}{\left({\text{CH}}_{\text{3}}\right)}_{\text{2}}\right)$.

Interpretation: The line-angle structure for the given condensed structural formula is to be stated.

Concept introduction: The structure in which carbon atoms are indicated by corners and ends of lines are called “line-angle” structures. In such structures, it is understood that each carbon atom is attached to enough hydrogen atoms to give each carbon atom four bonds. The lone pair of electrons is shown by a pair of dots.

Condensed formulas are those formulas which are written without showing all the individual bonds. “In condensed formulas, double or triple bonds are often drawn as they would be in a Lewis structures.”

(b)

Interpretation Introduction

To determine: The line-angle structure for the given condensed structural formula $\left({\left({\text{CH}}_3\right)}_2{\text{CHCH}}_2\text{Cl}\right)$.

Interpretation: The line-angle structure for the given condensed structural formula is to be stated.

Concept introduction: The Lewis structure shows the connectivity between atoms by identifying the lone pairs of electrons in a compound. Lewis structures are also called Lewis dot structures. The valence electrons around an atom are shown by dots. Bonds between atoms are shown by lines or by a dash (-) and the lone pair of electrons is shown by a pair of dots.

Condensed formulas are those formulas which are written without showing all the individual bonds. “In condensed formulas, double or triple bonds are often drawn as they would be in a Lewis structures.”
