Introduction Proline comprises with carboxyl and imine functional groups and it can also be called an amino acid. It is one of the most important amino acids that have several functions. It helps in maintaining blood pressure as well as forming collagen in humans. It can be incorporated into a protein molecule and is also called a critical component. Information regarding proline Proline is also called as L-proline and it falls under the category of non-essential amino acids. It mainly lies in the form of transparent crystals in nature. This kind of amino acid belongs to the imine functional groups. ... Read More
Introduction Promethium exists in the group off-block element bears the characteristics of the lanthanide group. The metal form of promethium is rare and that is the reason it does not have well-known physical and chemical properties. The salt form of this element consists of red or pink colour. The electronic configuration of this element is $\mathrm{[Xe]4f^{5}6s^{2}}$ as well as having 61 atoms. About promethium Promethium is called a chemical element bears the symbol of Pm. The number of atoms within this element is 61 and atomic mass is 145 g/mol. This element was invented by the famous scientist Mariinsky in ... Read More
Introduction Propane is nothing but a gas molecular entity that mainly acts as a propellant for food. Although it has no colour, consists of a faint petroleum-like odour. Two processes help in obtaining this gas and it is formed as a by-product of the processes petroleum refining and natural gas processing. Overview of propane Propane is also named as Propyl hydride, Dimethylmethane, and n-Propane. It has the chemical formula of C3H8 called three-carbon alkenes. It is a molecular entity of gas that acts like a food propellant. It was invented by Marcellin Berthelot, a French chemist in the year 1857. ... Read More
Introduction Ether is an organic compound that does not have any colour. They are characterised by a smell that feels very sweet and has various other traits. The formation of this compound happens by eliminating the moisture content present inside it. Chemical composition Ether is a very significant organic compound in the field of organic chemistry. This is a group that consists of different types of ether that have variable boiling and melting points. In general, ether group has a boiling point of 34.6° C. The point where it starts to melt is at a very low temperature which is ... Read More
Introduction The field of organic chemistry is full of several acids considered to be safe for consumption by every human being. The acetic acid is one such chemical compound used in a large number of commercial products produced in several industries. The functional group of this acid is called methyl. Aim of the experiment Figure 1 − Structure of Acetic Acid Acetic acid plays a very significant role in the daily life of human being. They are very common as human consider this acid as part of their diet. The aim of this experiment is to test the amount ... Read More
Introduction Base has three different types of definitions in the field of chemistry. All these definitions conclude same meaning of base. Base gives out electrons in solvent medium hence develop positive charge or excess proton in its molecular structure. Structure of bases The structure of bases is very unique to one another as these tend to make a proper compound for reduction of concentration of acids. Base gives out a pair of electron to the dilute solution of acid. The entire element starts to see a high concentration of acid start to transition over a phase which very diluted by ... Read More
Introduction Beryllium and Lithium are different from by the means of physical and chemical properties. The main difference between them is, Beryllium is diamagnetic and exists in white grey colour, whereas Lithium is paramagnetic and exists in silvery grey metal. They form two different kinds of cations of divalent and monovalent. What is Beryllium? Beryllium is an alkaline earth metal with atomic number of 4. It can be represented with the chemical symbol of Be. In this universe, it is considered one of the rarest chemical elements. It has a white-grey colour. Figure 1 − Atomic structure of Lithium ...

Introduction Boron family is important as; these elements play a major role in the ecosystem. They are essential for both plants and humans. For example, boron deficiency can stop plant growth while the excess amount of boron can inhibit the growth. Just like any other group, the boron family have some specific characteristics such as the pattern of electron configuration. What is Boron Family? The term boron family can refer to all the elements that belong to group 13. It is the first group in the p block of the periodic table. The periodic table and the position of the ... Read More
Introduction Many characteristics make the solution different from the Colloids. The properties can be the chemical nature or the light scattering tendency or even the particle solubility. Not only that but also many things such as the components particle size, nature, and filtration can differ from each other. Each type of mixture has its properties that help in the identification. What are Colloids? Colloids can be found in many things and many forms. The most common example of colloids is the water droplets in the fog. During the fog, those water molecules are dispersed in the gas. In daily life, ... Read More
Introduction Dichlorodiphenyltrichloroethane or DDT was first synthesised by Othmar Zeidler, an Austrian chemist in 1874. Paul Hermann Müller, a Swiss chemist discovered the insecticidal properties of DDTs in 1939. During World War II, it was used to prevent the spread of malaria, typhus and other insect-borne diseases among non-combatants and troops. It was also used to control the insect in crop and livestock production, homes, institutions, and gardens. What Is DDT? Dichlorodiphenyltrichloroethane or DDT is a chemical compound and the formula is $\mathrm{C_{14}H_{9}Cl_{5}}$. It is also called 1, 1, 1-trichloro-2, 2-bis(p-chlorophenyl) ethane. Under standard temperature and pressure (STP), pure DDT ... Read More
