Chapter 2, Problem 2.14P

Interpretation Introduction

Interpretation:

Out of the two structures, a structure with a stronger $\text{H}$- bond is to be determined and the reason is to be explained.

Concept introduction:

For a covalent bond, hydrogen bonding is the strongest intermolecular interactions that will occur between two molecules. For hydrogen bonding to occur, the molecule must possess at least one $\text{H}$- bond donor and at least one $\text{H}$- bond acceptor. As the number of potential $\text{H}$- bond donors and acceptors increases, the strength of hydrogen bonding increases. A potential H-bond donor is an H atom which is covalently bonded to a strongly electronegative atom such as N, O, or F and the H-bond acceptor is the neighboring electronegative atom which must possess a lone pair of electrons. The strength of hydrogen bonding also depends on the concentrations of charge in the H-bond donors and H-bond acceptors.
