Introduction Chemical properties of amines, basicity, and acylation of amines are considered for studying about amine compounds. Focusing on the certain compounds found in the organic chemistry, the present tutorial includes the definition of chemical properties of amine. The compound has single pair of electron and nitrogen atom attached with is called amine. This compound is considered the derivatives of ammonia, containing more than one hydrogen atoms. The alkyl or aryl group can replace these particular hydrogen atoms often. Based on these concepts, this tutorial discusses the chemical reactions are observed with amines. Basicity of Amines On a general ... Read More

Introduction Bismuth Subsalicylate is a commercial drug that is sold over the counter means it can be sold without any prescription. It has the chemical formula ${C_7H_5BiO_4}$. It was developed over 100 years back, in 1901, for the treatment and sanitation of cholera infection. First, in 1939 it was approved by FDA for the treatment of nausea, diarrhoea, and gastrointestinal infections. It is an insoluble salt of salicylic acid. It exhibits the property of antibacterial and antidiarrheal agents. It is used for the treatment of travellers' diarrhoea, nausea, stomach infection, antacid, heartburn, indigestion, etc. What is Bismuth Subsalicylate It is ... Read More

Introduction The scientific reason behind both the physical and the chemical change is important to understand the characteristics of both of these changes. The reversible and irreversible nature of any components is associated with both of these changes. In a physical change, an object’s basic components change in shape, size, and colour. The chemical changes are very much different as it leads to an irreversible change that cannot be avoided while any chemical experiments are undertaken. What is a chemical change? During a chemical change, the atoms and molecules are broken into pieces and form a new component. An individual ... Read More

Introduction Chemical change is the process by which new forms of matter are formed. Combining baking soda and vinegar, is the experiment through which the changes and features of chemical reactions are noticeable. This experiment also distinguishes physical change and chemical change clearly in a matter. The matter's properties are being understood by observing the chemical changes in them. Chemical changes can be observed in varied activities that are performed during daily life from the digestion of food to the explosion of fireworks, and the removal of grime by soap. A chemical change is a form of chemical reaction that ... Read More

Introduction The Birch reduction is a reaction where arenes are transformed into cyclohexadiene. Prof. Arthur J. Birch, an Australian chemist who determined the product's structure in the reduction reaction as a 1, 4-cyclohexadiene derivative in 1944, gave the reaction the name "Birch reduction." For the reduction of benzene (inactivated arenes), birch reductions generally use alkali metals (e.g., Li, Na, or K), which dissolve in Liq. ammonia to provide a solvated electron. Hence, the resulting solution is an astounding hue of blue, even though given metals are only faintly soluble in Liq. ammonia. The object has a deep blue colour because ... Read More

Introduction The Balz-Schiemann (BS) reaction was one of the first procedures for producing fluorinated aromatic compounds but is still commonly used today. The thermal breakdown of diazonium tetrafluoroborate by diazotization of the corresponding aromatic amines introduces a fluorine atom into aromatic rings in this process. This reaction is notably essential for the synthesis of fluorinated aromatic compounds, whose breakdown in the lack of solvent generally yields a reasonably excellent yield of aromatic fluorides. The BS reaction has been thoroughly studied or shown to be beneficial in the synthesis of aromatic halides. What is Balz Schiemann Reaction ? The BS reaction ... Read More

Introduction The availability of aluminium in a pure state is very rate due to its chemical properties. Additionally, it is one of the most abundant compounds on the Earth due to its availability of it as a compound state with other materials. “Alum and aluminium oxide” are the two most frequent particles discovered as the chemical properties of this material. This tutorial helps understand the usefulness of aluminium in the different prospective and shares knowledge regards the chemical properties of aluminium. Information about Aluminium The electron number of the aluminium is 13, which refers to that; it has exactly 13 ... Read More

Introduction At present, there are 118 elements that are known to us and from them, 92 elements occur naturally. The other metals within the total list are prepared with the help of artificial methods. However, elements are classified into several categories, that includes, metals, metalloids and non-metals based on their respective properties and are correlated with respect to their periodic table. There are several physical and chemical properties, that are noticed among metals. What are metals? Both metals and non-metals are found within our surroundings and are quite essential in their presence. Metals can be defined as the substances that ... Read More

Introduction Barium Carbonate has a molecular formula, (BaCO3). It is an inorganic chemical compound. It is tasteless and odourless. Like or similar to most of the other alkaline earth metal carbonates, it appears as white salt and it is insoluble or poorly soluble in water solution but, it is soluble in most of the acids, except sulphuric acid. It is one of the very important barium compounds commercially or economically. Although it is not soluble in pure water it is partially or slightly soluble in water saturated with carbon dioxide (CO2). It is used for the formation of rat poisons. ... Read More
