Chapter 8, Problem 8.18VP

(a)

Interpretation Introduction

Interpretation: The asked questions based on the given representation of the figures are to be answered.

Concept introduction: The higher is the number of bonds between the two atoms, the stronger is the bond.

A molecule with unsymmetrical stretch and net dipole moment absorbs infrared light and contributes to green house effect.

The most polar bond is of that is formed of the two atoms with he greatest electronegativity difference.

The formation of an ionic bond from its constituent ions causes the release of heat.

Lewis structures do not indicate the charges on the atom in a molecule due to the unbalanced valence electrons.

To determine: The hydrocarbon that has the strongest $\text{carbon}-\text{carbon}$ bond.

(b)

Interpretation Introduction

To determine: The hydrocarbon that has the weakest $\text{carbon}-\text{carbon}$ bond.

(c)

Interpretation Introduction

To determine: If the compounds represented by figure $\text{B}$ and $\text{G}$ absorbs infrared photon through an asymmetric stretch and contribute to the green house gas.

(d)

Interpretation Introduction

To determine: The most polar bond in the compounds represented by the figure $\text{C}$ and $\text{D}$ is to be labelled with the arrow and partial positive and partial negative notation.

(e)

Interpretation Introduction

To determine: The process that is exothermic.

(f)

Interpretation Introduction

To determine: The figure that represents the key limitation of Lewis structure.
