Chapter 8, Problem 10STP

Interpretation Introduction

Interpretation: The type of intermolecular bonding formed in the given drawing needs to be identified.

Concept Introduction: Intermolecular bonds are formed between atoms of two different molecules of the same and different type. In this bond formation, atoms from two different or the same molecules can show interactions.

Explanation of Solution

The given molecule is ${\text{H}}_{\text{2}}\text{O}$ . Here, one oxygen atom is covalently bonded with 2 H atoms. The drawing shows the interaction between two ${\text{H}}_{\text{2}}\text{O}$ molecules. Here, oxygen from one water molecule shows a bonding with the hydrogen atom of another water molecule. Here, the oxygen atom in both molecules has lone pair of electrons.

A hydrogen bond is formed between a molecule having a hydrogen atom covalently bonded with an electronegative atom (hydrogen bond donor) and another electronegative atom having lone pair of electrons (hydrogen bond acceptor).

Therefore, this bond formation is the formation of intermolecular hydrogen bonding.
