Chemical Bonding in Everyday Life

Chemical bonding is a fundamental concept in chemistry that describes the way atoms stick together to form molecules, which give substances their unique properties. From the water we drink to the plastics we use, chemical bonds play a crucial role in our daily lives.

Atoms are the fundamental building blocks of our universe. Chemical bonding arises, as atoms share or transfer electrons, creating strong attractive forces that hold them together. The three primary types of chemical bonding are ionic, covalent, and metallic.  Ionic bonding involves the transfer of electrons from one atom to another and creating oppositely charged ions that attract each other. Covalent bonding arises from the sharing of electrons between atoms. Metallic bonding is unique to metals and arises from the delocalization of electrons among positively charged metal ions. This creates a “sea of electrons” that can move freely within the metal lattice.

Water is essential for human survival and stands as a prime example of chemical bonding in action. Each water molecule (H2O) comprises two hydrogen atoms covalently bonded to a single oxygen atom. Water has some remarkable properties thanks to hydrogen bonding.  Hydrogen bonding is a specialized type of dipole-dipole interaction. Surface tension, a consequence of intermolecular forces, enables water to form droplets, bead up on surfaces, and rise in narrow tubes, essential processes for plant life and water transport in living organisms. Water’s high specific heat capacity allows it to absorb and store a significant amount of energy helping to regulate body temperature and mitigate temperature fluctuations.

For example, ice floats on top of liquid water because it’s less dense than liquid water. This unusual property is due to the way hydrogen bonds arrange themselves in the solid state, creating more space between water molecules. Without hydrogen bonding, ice would sink, and our planet’s climate would be vastly different. During the winter season, fish and other living beings under the river rely on this property to survive. The layer of ice on top of the water provides a protective barrier, preventing the water beneath from freezing completely and allowing aquatic life to continue thriving. This is just one of the many ways in which hydrogen bonding plays a vital role in sustaining life on Earth.

Polymers are large molecules made up of many repeating units called monomers. They are found naturally in nature, such as cellulose in plants and proteins in animals, and are also synthesized artificially for various applications. Polyethylene, polypropylene, and polyester are common examples of synthetic polymers used in plastics, fibers, and textiles. Polymers are created through a process called polymerization, where monomers are joined together through chemical reactions. In some cases, polymerization involves the formation of covalent bonds between monomers while in others, it involves ionic or metallic bonding. The type of bonding and the arrangement of monomers determine the properties of the resulting polymer. The properties of polymers, such as their strength, flexibility, and durability, make them indispensable in our daily lives. They provide us with lightweight materials for construction, durable fabrics for clothing, versatile plastics for packaging, and countless other applications.

One common application of polymers is in the production of plastic pipes used in water supply systems. Polyvinyl Chloride (PVC) pipes, for instance, are a popular choice for water distribution due to their resistance to corrosion, ease of installation, and low maintenance cost. PVC pipes are made from a combination of vinyl chloride monomers, which are polymerized to form a long chain of molecules. The resultant pipe is strong, flexible, and resistant to cracking, making it an ideal material for water transmission. Additionally, PVC pipes can be easily connected using solvent welding techniques, ensuring a watertight seal. The use of PVC pipes has revolutionized the plumbing industry by providing a reliable and efficient means of delivering clean water to homes and businesses.

Though chemical bonding is not visible to the naked eye, is the invisible hand that weaves the webs of our world together. From the life-giving properties of water to the versatile applications of polymers, chemical bonding plays a fundamental role in shaping our everyday experiences. By understanding the different types of chemical bonds and their applications, we can better appreciate the intricate complexity of the world around us and harness this knowledge to create innovative solutions for a better future.
