Chapter 6, Problem 26QRT

(a)

Interpretation Introduction

Interpretation:

The molecular formula ${\text{C}}_{21}{\text{H}}_{44}$ is straight-chain as an alkane, an alkene or alkynes have to be classified.

Concept Introduction:

The formulas of alkanes are ${\text{C}}_{\text{n}}{\text{H}}_{\text{2n+2}}\text{, for n = 1}$ and higher.  Each multiple bond removes two electrons. 

The formulas of alkenes are ${\text{C}}_{\text{n}}{\text{H}}_{\text{2n}}\text{, for n = 2}$ and higher.

The formulas Covalent Bonding of alkynes are ${\text{C}}_{\text{n}}{\text{H}}_{\text{2n-2}}\text{, for n = 2}$ and higher.

(b)

Interpretation Introduction

Interpretation:

The molecular formula ${\text{C}}_4{\text{H}}_6$ is straight-chain as an alkane, an alkene or alkynes have to be classified.

Concept Introduction:

(c)

Interpretation Introduction

Interpretation:

The molecular formula ${\text{C}}_8{\text{H}}_{\text{16}}$ is straight-chain as an alkane, an alkene or alkynes have to be classified.
