Inorganic Chemistry

What is Inorganic Chemistry?

The word organic refers to the compounds which contain the carbon atoms in it. So the branch of chemistry that deals with the study of compounds, which does not consist of carbon-hydrogen atoms in it, is called ‘Inorganic Chemistry.’ In simple words, it is opposite to that of Organic Chemistry. The substances which do not have carbon-hydrogen bonding are the metals, salts, chemical substances, etc.

On this planet, there are known to exist about 100,000 number of Inorganic compounds. Inorganic chemistry studies the behaviour of these compounds along with their properties, their physical and chemical characteristics too. The elements of the periodic table except for carbon and hydrogen, come in the lists of Inorganic compounds.

Many of the elements are technologically important: titanium, iron, nickel and copper, for example, are used structurally and electrically. Second, the transition metals form several useful alloys, with each other and with other metallic elements.

Chemistry Definition

Chemistry is the study of the substances of which matter is composed. Chemistry is heavily experimental because you can only study reductions if you totally mix substances together. Luckily, you don’t need to risk your health and safety to understand chemistry better because brave scientists already did. There are over a hundred elements that make up the matter of our world and universe. They combine to make thousands and thousands of compounds.

A chemical compound is made up of atoms of different elements joined together by a chemical bond. The bonds are so strong that the compound acts as if it were a single substance. The joined atoms form molecules and the molecules connect together to make the compound.

A chemical formula is a notation used by scientists to show the number and type of atoms present in a molecule using atomic symbols and numeric subscriptions. A chemical formula is a simple representation, in writing, of a three-dimensional molecule that exists. A chemical formula describes a substance, down to the exact atoms that make it up. There are three basic types of chemical formula, the empirical formula, the molecular formula and the structural formula.

Organometallic Chemistry

Organometallic Chemistry, an interdisciplinary science in Inorganic Chemistry, has grown at a phenomenal pace during the last three to four decades. On the academic plane, efforts to elucidate the nature of bonds in the ever increasing list of exciting organometallic compounds have led to a clearer understanding of the nature and variety of chemical bonds.

Organometallic compounds are primarily used as homogeneous catalysis agents in industries. The topics covered in this book offer the readers new insights in the field of organometallic chemistry.

Organometallic chemistry is an organometallic compound study. Because many compounds without these bonds are chemically identical, an alternative may be compounds containing metallic bonds of a mostly covalent nature. Organometallic chemistry blends elements of inorganic chemistry with organic chemistry.

Transition Elements

A transition element may be defined as one which possesses partially filled d-orbitals in its penultimate shell. This conceptual definition is useful as it enables us to recognize a transition element merely by looking at its electronic configuration. This definition excludes zinc, cadmium and mercury from the transition elements as they do not have a partially filled d-orbital. However, they are also considered as transition elements, because their properties are an extension of the properties of transition elements in inorganic chemistry. In fact, the zinc group serves as a bridge between the transition elements and the representative elements.

The most notable characteristics shared by the 24 elements concerned are that they are all metals and that most of them are hard, solid and lustrous, have high melting and boiling points and are good conductors of heat and electricity. The range in these properties is considerable; hence, the statements are comparable to the general properties of all the other elements.

Coordination Chemistry

Coordination compounds found their applications long before the establishment of inorganic chemistry. A systematic investigation of structure and bonding in coordination chemistry began with the inquisitiveness of Tassaert which was extended by distinguished chemists like Wilhelm Blomstrand, Jorgensen and Alfred Werner until the end of the nineteenth century. In the events, Werners coordination theory became the base of modern coordination chemistry.

P-Block Elements

The elements placed in group 13 to group 18 of the periodic table constitute the p-block. The properties of inorganic chemistry p block elements like that of other block elements are greatly influenced by their atomic size, ionization enthalpy, electron gain enthalpy and electronegativity. The absence of d–orbitals in the second period and presence of d- or f-orbitals in heavier elements has a significant effect on the properties of the elements and therefore, heavier p-block elements differ from their lighter congeners.

Classification of Inorganic Compounds

The organic compounds that are classified under Inorganic chemistry are:

  • AcidsAcids are those compounds that dissolve in water and generate hydrogen ions or H+ Ions. The examples of acids include Hydrochloric acid, citric acid, sulphuric acid, vinegar, etc. One example of the acidic reaction is shown below-Hydrochloric acid + water → H+ + Cl
  • BasesA base is a type of substance or a compound that produces hydroxyl ions when kept in water. The bases like potassium hydroxide, calcium hydroxide, ammonia, sodium hydroxide produce OH- ions when dissolved in water.Potassium Hydroxide + H2O → K+ + OH-
  • SaltsAs you might be familiar with the word ‘Salt’. The substances obtained as a result of the reaction between an acid and a base are called Salts. The table salt of sodium hydroxide is one of the typical examples of salts.
  • OxidesThe compounds which consist of one oxygen atom called Oxides.

Types of Reactions and Examples

There are about four types of chemical reactions of Inorganic chemistry namely combination, decomposition, single displacement and double displacement reactions.

  1. Combination ReactionsAs it is in the name ‘Combination’, here two or more substances combine to form a product which is called a Combination reaction. For example:Barium + F2 → BaF2
  2. Decomposition ReactionIt is a type of reaction where a single element splits up or decomposes into two products. For example:FeS → Fe + S
  3. Single Displacement ReactionsA reaction where a single atom of one element replaces another atom of one more element. For example:Zn (s) + CuSO4 (aq) → Cu (s) + ZnSO4 (aq)
  4. Double Displacement ReactionsThis type of reaction is also called ‘metathesis reactions’. Here two elements of two different compounds displace each other to form two new compounds. For example:CaCl2 (aq) + 2AgNO3 (aq) Ca(NO3)2 (aq) + 2 AgCl (s)

Applications of Inorganic Chemistry

Inorganic chemistry finds its high number of applications in various fields such as Biology, chemical, engineering, etc

  • It is applied in the field of medicine and also in healthcare facilities.
  • The most common application is the use of common salt or the compound Sodium hydroxide in our daily lives.
  • Baking soda is used in the preparation of cakes and other foodstuffs.
  • Many inorganic compounds are utilized in ceramic industries.
  • In the electrical field, it is applied to the electric circuits as silicon in the computers, etc.
