Chapter 4, Problem 17CTQ

Interpretation Introduction

Interpretation: Whether below structures are $\text{H}-\text{bond}$ donor, $\text{H}-\text{bond}$ acceptor or neither should be determined.

  

Concept introduction: Substances are said to be $\text{H}-\text{bond}$ donors if these can transfer ${\text{H}}^{+}$ to other substances that require it. Substances that accept ${\text{H}}^{+}$ donated by $\text{H}-\text{bond}$ donors are termed as $\text{H}-\text{bond}$ acceptors. Such substances have lone pair of electrons on them that can be donated. For example ${\text{H}}_{\text{2}}\text{O}$ is $\text{H}-\text{bond}$ acceptor whereas $\text{HCl}$ acts as $\text{H}-\text{bond}$ donor.
