An understanding of living organisms, including the human being have reached us through chemistry, the science dealing with materials, their composition, and the changes, which they undergo. Chemistry and chemical changes help us understand the human body. Chemistry fits into our lives. It offers new chemical frontiers and tells us what benefits may flow from them. Chemistry contributes to our existence, our culture, and our quality of life. Chemistry is concerned with the changes we see around us, like the rusting of iron, growing of grass, burning of wood and many more. Without these changes or chemical reactions our Planet Earth would be lifeless. A plant takes carbon dioxide from the air and water from the soil to produce carbohydrates through a wondrous series of chemical reactions called photosynthesis. All living processes are chemical reactions. Everything we use, wear, live in, ride in, and play with is produced through controlled chemical reactions. Chemists design reactions that will convert chemical substances we find around us into chemical substances that serve our needs. Chemistry answers the needs of our society through a deep understanding of the factors that govern and furnish control of chemical reactions. It plays a critical role in man’s attempt to feed the world population, to tap new sources of energy, to clothe and house humankind, to provide renewable substitutes for dwindling or scarce materials, to improve health and conquer disease, and to monitor and protect our environment. Because of this responsiveness to human needs, chemistry has become a crucial factor in the nation’s economic well-being. Aside from that, our culture believes that learning about our place in the universe is not enough reason for encouraging scientific inquiry. Nothing concerns humans more than questions about the nature of life and how to preserve it. Since all life processes are brought about by chemical changes, understanding chemical reactivity is a vital...
