Chapter 20, Problem 1STP

(a)

Interpretation Introduction

Interpretation: Whether ${\text{C}}_3{\text{H}}_6$ is a saturated hydrocarbon or not needs to be determined.

Concept Introduction : Saturated hydrocarbons: It is a hydrocarbon in which all carbon−carbon bonds are singlebonds.

Answer to Problem 1STP

  ${\text{C}}_3{\text{H}}_6$ is not a saturated hydrocarbon.

Explanation of Solution

Lewis structure of ${\text{C}}_3{\text{H}}_6$ is as follows:

  

Since, the structure has a double bond between carbon-carbon atoms, therefore ${\text{C}}_3{\text{H}}_6$ is not a saturated hydrocarbons as saturated hydrocarbons has single carbon-carbon bond.

(b)

Interpretation Introduction

Interpretation: Whether ${\text{C}}_2{\text{H}}_4$ is a saturated hydrocarbon or not needs to be determined.

Concept Introduction : Saturated hydrocarbons: It is a hydrocarbon in which all carbon−carbon bonds are singlebonds.

Answer to Problem 1STP

  ${\text{C}}_2{\text{H}}_4$ is not a saturated hydrocarbon.

Explanation of Solution

Lewis structure of ${\text{C}}_2{\text{H}}_4$ is as follows:

  

Since, the structure has a double bond between carbon-carbon atoms, therefore ${\text{C}}_2{\text{H}}_4$ is not a saturated hydrocarbons as saturated hydrocarbons has single carbon-carbon bond.

(c)

Interpretation Introduction

Interpretation: Whether ${\text{C}}_4{\text{H}}_{10}$ is a saturated hydrocarbon or not needs to be determined.

Concept Introduction : Saturated hydrocarbons: It is a hydrocarbon in which all carbon−carbon bonds are singlebonds.

Answer to Problem 1STP

  ${\text{C}}_4{\text{H}}_{10}$ is a saturated hydrocarbon.

Explanation of Solution

Lewis structure of ${\text{C}}_4{\text{H}}_{10}$ is as follows:

  

Since, the structure has a single bond between carbon-carbon atoms, therefore ${\text{C}}_4{\text{H}}_{10}$ is a saturated hydrocarbons as saturated hydrocarbons has single carbon-carbon bond.

(d)

Interpretation Introduction

Interpretation: Whether ${\text{C}}_5{\text{H}}_{10}$ is a saturated hydrocarbon or not needs to be determined.

Concept Introduction : Saturated hydrocarbons: It is a hydrocarbon in which all carbon−carbon bonds are singlebonds.

Answer to Problem 1STP

  ${\text{C}}_5{\text{H}}_{10}$ is not a saturated hydrocarbon.

Explanation of Solution

Lewis structure of ${\text{C}}_5{\text{H}}_{10}$ is as follows:

  

Since, the structure has a double bond between carbon-carbon atoms, therefore ${\text{C}}_5{\text{H}}_{10}$ is not a saturated hydrocarbons as saturated hydrocarbons has single carbon-carbon bond.
