Chapter 5, Problem 12Q

(a)

Interpretation Introduction

Interpretation:

The structural formula of n-decane ${\text{(C}}_{10}{\text{H}}_{22})$ has to be drawn.

Concept introduction:

Structural formula:

The arrangement of atoms in the molecule of a compound.  The general molecular formula of alkane is ${\text{C }}_{\text{n}}{\text{H }}_{\text{2}}{}_{\text{n}}{}_{\text{+}}{}_{\text{2}}$, n is the number of carbon atom.

(b)

Interpretation Introduction

Interpretation:

The chemical formula for n-nonane (9 C atoms) and n-dodecane (12 C atoms) has to be drawn.

Structural formula:

The arrangement of atoms in the molecule of a compound.

The general molecular formula of alkane is ${\text{C }}_{\text{n}}{\text{H }}_{\text{2}}{}_{\text{n}}{}_{\text{+}}{}_{\text{2}}$, n is the number of carbon atom.
