Chapter 8, Problem 50A

Interpretation Introduction

Interpretation:

It is to be explained why compounds having $\text{C-N}$ and $\text{C-O}$ single bonds can form coordinate covalent bonds with ${\text{H}}^{\text{+}}$ but compounds containing only $\text{C-H}$ and $\text{C-C}$ single bonds cannot.

Concept introduction:

When two or more atoms, molecules, or ions join together chemically to form a compound, this process is known as chemical bonding.

Explanation of Solution

When two electrons are needed to complete an octet, one atom provides a pair of electrons, while the other atom only shares them. So, there is a need for unshared pairs in compounds, but there are none is $\text{C-H}$ bonds and $\text{C-C}$ bonds.
