Inorganic Chemistry

Inorganic Chemistry is the examination of the properties and behavior of both inorganic and organometallic compounds. Although, it focuses on all the chemical compounds which do not have an organic (carbon-based) component to them, it is not truly distinct from the study of Organic Chemistry. The applicability of Inorganic Chemistry is not limited to the laboratory as it also heavily extends into the fields of industry, medicine and even agriculture. Inorganic Chemistry explores the basic properties and rules of inorganic compounds, whether it is their patterns in the periodic table or their general behavior in a chemical reaction. The primary challenge, as is with all chemistry disciplines, is knowing when to apply these rules given the chemical system being analyzed. Such an understanding can help predict the type of reaction which occurs, whether it is a combination reaction, decomposition reaction, single displacement reaction and also the outcome of each type of inorganic reaction. Many chemists also combine studying Inorganic Chemistry with Thermodynamics, as an energetic approach towards inorganic reactions has proven to be very useful. For example, a classic concept in the field of inorganic chemistry is the Born-Haber Cycle. Looking at such a process from a thermodynamic point of view can help assess the different levels of reaction energies. Although inorganic chemistry and thermodynamics are considered different disciplines of chemistry, using them together has been useful in providing better information regarding the chemical nature of reactions. Thus, studying Inorganic Chemistry is essential for successful prediction of inorganic chemical behavior.
